Why are the leaves on the trees different? The moment of awakening: how the buds of different trees open. When leaves begin to appear on the trees.

Ulanova L. A., Jordan S. O. Guidelines on organizing and conducting walks for children 3-7 years old.

Target- repeat the names of the trees. Discuss the structure of a tree (trunk, branches, leaves).

Progress of the walk

Observation: Pay attention to the fact that after winter sleep every tree comes to life. Spring juices rise up the trunk to the branches, fill the buds, and they inflate, swell, just about ready to burst. Examine the buds on the branches: in poplar they are long, sticky, fragrant, and in birch they are round and small. Look closely at the emerging leaves. On birch - wrinkled, sticky, accordion-like, dark green. On poplar - shiny, sticky, dark green. When examining the buds with older children, explain that some trees wake up earlier, others later. To tell about healing properties birch and pine buds. Touch the leaves, find similarities and differences. Watch the leaves grow. Observe the planting of trees and shrubs and digging of the earth. Explain why this is being done.

Didactic games

"Look and describe"- children examine and describe the plants proposed by the teacher. The goal is to consolidate children's knowledge about changes in nature in the spring. Teach to observe nature, see the beauty of the landscape. Foster a caring attitude towards nature.

"What leaf"- children describe the leaf of the tree proposed by the teacher. The goal is to use relative adjectives in speech.

Exercises to develop fine motor skills of the hands

Lay out leaves from stones.
By fastening the leaves with a twig, make a belt or wreath, or a hat.

Work and individual physical exercises

Clear the ground of old leaves. Plant a tree or shrub.
Jump to the leaf (high jump).

Outdoor games

"Gawker." The goal is to develop attention, practice throwing and catching the ball. Progress of the game: Children stand in a circle and begin to throw the ball, calling by name the one who should catch. The one who drops the ball stands in a circle and, according to the children’s instructions, performs 2-3 exercises with the ball.

"Hunter". The goal is to practice throwing and throwing a ball. Progress of the game. One is chosen as the “hunter”, all the rest are chosen as “game”. The “hunter” plays ball, while the others walk around the court. After 3-4 exercises he shouts: “Game!” Everyone stops, and from his place he spots one of the children. The Stained One becomes the hunter's assistant. The game continues until a certain number of helpers appear (3-5 people).

In this article we have collected material on the topic “tree leaves” and “tree structure”. Acquaintance with a tree begins for a child in his earliest childhood.

Each yard has its own good-natured giant, who will happily provide shelter from the scorching sun, rain, and share fallen leaves and dry twigs for everyone. However, many children perceive trees as nameless companions, without thinking that each of them has its own name, has a complex structure and performs important tasks. Therefore, with a deeper study of trees, kids make many discoveries for themselves.

For example, children will be interested in learning what parts a tree consists of. To do this, we use a schematic image of a tree and talk about each part of it:


  1. The roots of a tree are its foundation. They feed the tree by absorbing nutrients dissolved in the water and also keep it upright. The larger the tree, the richer its root system.
  2. The trunk of a tree is like its body. All substances extracted by the roots pass upward along the trunk, and branches begin to extend from the trunk. It is important to note that a real tree has one trunk, but shrubs have several, even large, trunks.
  3. Tree branches - support for leaves; It is on the branches that buds form, from which leaves and flowers then appear. Nutrients also pass through them. Over time, the branches become wider and harder (woody), and new branches appear from them.
  4. The foliage of a tree is an organ that allows the tree to exchange substances with the environment. Thanks to the leaves, the tree absorbs carbon dioxide, which is harmful to humans, from the air, here organic substances are formed from it under the influence of sunlight, and through the leaves the tree releases the oxygen that we breathe.
  5. All the leaves and branches of the tree form its crown - a lush cap that provides shade and shelters us from the rain.

Having studied the structure of a tree, you can move on to the next stage - find out how it comes into being. Where and how do trees grow? The answer to this question can be depicted in the form of a circular diagram.


So, let's look at everything life cycle fruit tree:

The seed is the source of life for every plant, including trees. It contains a small germ and an initial supply nutrients, which the embryo needs in order to germinate through the seed coat. Once in the soil, the embryo begins to actively develop, hatches through the shell, grows and sends out roots, with which it absorbs from the ground the substances necessary for its growth.

After many years, the embryo turns into a tree, which, having reached a certain age, acquires the ability to reproduce its own kind.

In the spring, buds form on the branches of the tree, in which an organ of amazing beauty and smell develops - a flower.

The flower of a fruit tree is designed in such a way that when pollinated (by wind or insects), a small rudiment of the fruit is formed in it.


The beginning of its development and rapid growth occurs in the spring, when buds are actively formed on the branches, from which leaves and flowers subsequently appear. It is not without reason that they say that in spring trees come to life after winter sleep.

In summer, trees appear before us in all their glory. They constantly interact with the outside world, feed, and replenish supplies of substances necessary for their life. Tree leaves work continuously in the summer, turning into a real processing factory. carbon dioxide, and the production of oxygen and nutrients from it.

All vital processes in the tree decline: daylight hours become shorter, and the amount of sunlight is not enough for the formation of new chlorophyll molecules in the leaves, so the foliage gradually changes its color and falls off. Falling leaves not only saves the tree's strength, which it will need to survive the harsh winter, but also saves tree branches from breaking off, which can occur under the weight of fallen snow.

The tree seems to freeze. It economically uses the reserves accumulated over the summer and looks forward to the arrival of the first spring warmth.

But not all trees go through such a cycle of transformations, but only those that have leaves, that is, deciduous. But trees whose branches are covered with needles (conifers) look the same all winter as they do in summer.

The most famous coniferous tree is. Of course, it became famous thanks to the Russian tradition of decorating spruce branches on New Year's Eve. Spruce reproduces with the help of cones that form during the summer.

But the most common deciduous trees are:

  • - a tree with bright berries and beautiful jagged foliage that looks especially impressive in the fall. There is a version that it was called rowan because its leaves are quite small and, when the wind blows, they tremble, causing ripples in the eyes of those who look at it.

  • Birch is a symbol of Russia, unique tree with white bark. Its very name comes from a Slavic word meaning “to glow, to turn white.” Birch is also interesting for its flowers, which look like earrings, and the fact that its branches are very long and thin, they seem to hang down.

  • Poplar is a frequent companion of human habitation. Poplars are planted near houses because they grow quickly - which means they begin to purify the air early and absorb well excess moisture. IN wildlife poplar is often found in wetlands, which is why it got its name, which translated from Slavic means “swampy place, swamp.” Poplar fruits are capsules from which seeds spill out, covered with many silky hairs - poplar fluff. This fluff causes a lot of inconvenience to people, so poplars are often pruned, leaving only non-fruit-bearing branches at the top.
  • Oak is a giant tree, especially revered by our ancestors. Its fruits - acorns - were used to prepare a drink that replaced coffee, but also greater application People have found oak bark and wood, which is distinguished by its strength and beautiful color.

  • Maple has beautiful leaves with sharp edges. Sweet, aromatic maple syrup is obtained from its sap.

  • Elm is a tree whose wood, branches and bark have been used by people since ancient times to make furniture, tools and even weapons. Elm bark (bast) is strong and flexible; it was used to bind various objects, which is why the tree got its name. Shoes were woven from bast.

  • Chestnut is a tree with unusual fruits, the core of which resembles a nut. It is believed that the word “chestnut” has the same root as the word “porridge”, since the fruits of the chestnut were often eaten.

  • Willow is a tree with unusual long branches and narrow leaves. Its name comes from the word “twist”, which is explained by the main use of willow branches - they were used to twist baskets and weave furniture.

In order to better remember the names of trees, you can play a simple game: mix cards with pictures of leaves and the trees themselves, and then match them and name them.

The leaves can be used to make a very interesting visual aid for children. To do this you will need to collect leaves different types and laminate them.


We cut out the leaves slightly away from the edge.


We have a live guide to learning the types of leaves.


Print out the names of the trees where you collected the leaves from on a separate piece of paper. We compare the name of the tree with the leaf itself, studying and remembering its shape and structural features.


Images of leaves are more clear on coloring pages, where you can examine their outline and color them depending on the expected time of year and the shades characteristic of a particular tree.

Walk “First leaves on the trees”

Subject: « First leaves on the trees»

Tasks: To develop in children the ability to purposefully carry out observation, identify changes that have occurred with trees since the previous observation. Develop in speech concepts related to structure trees(trunk, branches, leaves) . Cultivate curiosity and love for nature.

Progress of the walk

Observation

Pay attention to the fact that after winter sleep every tree. Spring juices rise up the trunk to the branches, fill the buds, and they inflate, swell, just about ready to burst. Look at the buds on the branches: in poplar they are long, sticky, fragrant, and in birch they are round and small. Look closely at the appeared leaves. On the birch - wrinkled, sticky, accordion-like, dark green. On poplar - shiny, sticky, dark green.

When examining the kidneys with children, explain that they are alone trees wake up earlier, others - later. Talk about the healing properties of birch and pine buds. Touch leaves, find similarities and differences. Watch it grow leaves. Watch the landing trees and shrubs, digging up the earth. Explain why this is being done.

Autumn leaf fall

Autumn leaf fall is an unusually bright and amazing natural phenomenon that amazes with its beauty. Looking at the flying golden leaves that spread in soft carpets, the question certainly arises: how does this process work and why, in fact, do the leaves fall in the fall?

Many tree species shed their leaves to survive adverse weather conditions. In the tropics and subtropics, leaves fall at the beginning of the dry season; in temperate regions, trees lose their leaves in the fall as cold weather approaches. Trees that shed their leaves at certain times of the year are known as deciduous trees. Trees whose leaves do not fall are called evergreen trees.

Most types of deciduous trees have broad leaves that fall off in cold or dry weather. Evergreen trees, unlike deciduous trees, grow in humid, warm climates or have needles that are weather-resistant.

Interesting fact: Evergreen trees retain their leaves throughout the year because their foliage is covered with wax, which protects against cold, and their cells contain antifreeze agents. chemical substances, which prevent the tree from freezing when low temperatures environment. Deciduous trees, on the other hand, are very susceptible to cold.


Evergreen trees retain their foliage throughout the year

Reasons for leaf fall:

  • duration daylight hours;
  • leaf damage;
  • arid climate;
  • cold climate;
  • tree pollination.

Length of daylight


Destruction of chlorophyll in the leaf during shortening of daylight hours

In autumn, the length of daylight hours gradually decreases. As exposure to daylight decreases, chlorophyll production decreases in leaves - green pigment, through which the plant absorbs sunlight and then converts it into nutrients; and the process of photosynthesis (which is carried out with the participation of chlorophyll) slows down until it stops.

Interesting:

Why is there a lot of water when baking chicken?

As a result, the production of sucrose, which plants use as food, stops and, consequently, the supply of nutrients to the tree is limited. To reduce the need for nutrients and resist cold or drought, trees shed their leaves.

Interesting fact: It has been noticed that forest trees shed their leaves faster than urban ones. This is due to the fact that there is more lighting in the city, including artificial lighting (lanterns, light from windows, cars, etc.).

Leaf damage

By late summer, the leaves have been damaged by insects, disease or general wear and tear and are ready to be renewed. As fall arrives, trees face low ambient temperatures, cold winds and other conditions that also damage leaves. For these reasons, the leaves fall off. In addition, in addition to nutrients, harmful substances (metabolites, excess mineral salts) are collected in the leaves. Therefore, by getting rid of leaves, the plant is cleansed.

Arid climate


Deciduous trees shed their leaves during drought to avoid drying out.

In hot weather, leaves evaporate a lot of moisture. The roots of the tree, while supplying the leaves, lose a large number of water. Coniferous foliage, so-called. evergreen trees are not subject to falling off, since their needles, occupying small area surfaces require less moisture compared to deciduous trees. Thus, deciduous trees shed their leaves during dry periods to reduce the need for moisture and avoid drying out.

Cold climate

In autumn, trees, sensing the reduction in daylight and lower air temperatures, begin to prepare for the cold. To conserve sufficient water and energy resources for winter period, plants accumulate nutrients and get rid of leaves. This process occurs cyclically and does not harm the plant. This is how autumn leaves begin to fall.

Interesting:

Why are there red buses and telephone booths in London?

Nutrient Accumulation

Trees collect valuable nutrients (nutrients) from leaves and store them in the roots for further application. Chlorophyll (the pigment that colors leaves green color) is the first to decompose into batteries. By the way, in connection with this, the leaves change color in the fall from green to orange, crimson, and gold.

Separating leaves from a tree


A separating layer of cells separates the leaf from the branch, resulting in the process of leaf fall

Leaves are cut from the tree by a detachment layer, which forms where the leaf stem meets the branch and is a collection of cells. As the autumn days shorten, this layer clogs the vessels on the leaf stem, which move water into the leaf and nutrients into the tree. Once the stem is clogged, the layer becomes dry and scaly and, through decomposition, separates the leaf from the tree. In the spring, in place of fallen leaves, new stems appear and leaves grow.

Trees, having gotten rid of their leaves, enter a state of suspended animation, which is compared to deep sleep. At this time, the plant uses nutrient reserves deposited in the summer.

Benefits of fallen leaves


Fallen leaves continue to benefit trees

Fallen leaves do not lose environmental significance. When decomposing them useful material flow into the soil and feed future generations of plant and animal life. This gives the tree the nutrients it needs to grow new leaves. In addition, the layer of discarded leaves covering the soil warms the tree and protects it from freezing during the cold season.

Seasons are seasons characterized by weather and temperature. They change depending on the annual cycle. Plants and animals adapt well to these seasonal changes.

In the tropics it is never very cold or very hot; there are only two seasons: one is wet and rainy, the other is dry. Near the equator (the imaginary midline) it is hot and humid throughout the year.

Temperate zones (outside the tropics) have spring, summer, autumn and winter.

Usually, the closer to the Northern or South Pole, the cooler the summer and colder the winter.

In three spring months, nature manages to change beyond recognition. In March, she is just beginning to awaken from hibernation. The spring heat is not enough to make the snow and ice blocks melt, but the air gradually warms up, preparing all living things for a gradual awakening; the first cumulus clouds appear, which still soar very high.

Astronomers consider the beginning of spring to be March 21–22, the moment of the vernal equinox, when day is equal to night, and the end to be June 21–22, the longest days of the year.

For naturalists, spring begins with the arrival of rooks (on average March 19) and the flow of sap from the Norway maple (March 25).

This season is divided into three periods: early spring- before the snow melts in the fields (until half of April), middle spring - before the bird cherry blossoms (until half of May) and late spring- before the apple and lilac trees bloom (before the beginning of June).

Phenomena in inanimate nature.

In the second half of March, the days become noticeably longer and the nights become shorter; The sun rises higher and higher at noon above the horizon, its rays fall more directly on the earth and warm it up more strongly. The snow becomes loose, begins to melt, and open places thawed patches form.

In the second half of March, the first cumulus clouds appear.

They are very beautiful, looking like snow-white, dome-shaped masses with smooth bases. Clouds usually appear in the morning or at noon due to the heating of the air adjacent to the ground; in the evening, when the rising currents weaken, they begin to disappear and melt.

In the first half of April the snow melts off; The streams formed when it melts run down to reservoirs.

Ice drift usually begins in mid-April. Shortly before this, edges appear near the shore - narrow strips of water. Under the influence of water and sun, cracks form in the ice, it splits and moves away. Ice floes, crowded and jostled, rush down the river, hitting the banks and piles of bridges. In the middle of the river, ice floes move faster than near the banks. Along the way they melt. The river is freed from the ice cover, overflows its banks and overflows. The flood begins.

Usually the first thunderstorm occurs in early May.

At this time and later, sudden cold snaps often occur with frosts, from which plants, especially fruit and berry plants, suffer greatly.

Spring awakening of trees. Soon after thawed patches appear, the trees awaken: they begin to flow sap. This phenomenon is revealed if you pierce the bark with a thick needle: a sweet transparent liquid flows out of the rakka; in air it oxidizes and acquires a reddish color.

Extracting sap causes great harm to trees.

Sap flow is a complex physiological process. The roots begin to actively absorb water from the thawing soil, it dissolves the plant’s winter reserves of nutrients and moves in the form of a solution along the trunk and branches to the buds.

Swelling and budding.

Top 16 primroses among shrubs and trees

Ten days after the start of sap flow, swelling of the buds becomes noticeable, in which rudimentary shoots are located under the protective bud scales.

Wind-pollinated trees and shrubs bloom before they are covered with leaves, or at the very beginning of their development.

Alder and hazel are the first to bloom in the second half of April, and among those pollinated by insects, willow. The buds of the willow are tightly covered with brown scales that look like caps.

Having shed them, the buds look like fluffy balls consisting of hairs that protect the flowers from sudden fluctuations in temperature and rain.

In April, most of the trees are still bare, but the integumentary scales of the swollen buds are already moving apart, and the tailbones of the leaves appear from them.
The appearance of leaves. The young leaves of some trees are covered with a sticky fragrant substance, while others have a fluff that protects them from the cold.

The light green color of the trees is tender and transparent at this time.

At the end of April, bird cherry and birch buds bloom; in the first half of May - buds of maple, yellow acacia, apple and pear trees, and then - oak and linden.

In late spring, in the second half of May, the real blossoming of spring begins. Bird cherry blossoms, at the same time - black currants, a little later - wild strawberries and fruit trees, lilac, rowan and most herbaceous plants.

In the last days of May, the fruits of aspen and willow ripen.

The petals of apple and lilac flowers fall off - spring ends, summer begins.

Biology Spring phenomena in plant life

Spring is the time for nature to awaken. According to the calendar, spring begins on March 1st. In nature, spring comes into its own with the beginning of sap flow in the trees, earlier in the south and later in the north on March 1.

The spring movement of sap in trees and shrubs is the first sign of spring. It occurs after the soil thaws and water from the roots begins to flow into all organs of the plant. At that time leaves Not yet.

Water accumulating in cells plant stems, dissolves the organic substances stored in them. These solutions move to the swollen and blooming kidneys. Already at the beginning of March, spring sap flow begins in Norway maple, earlier than in other trees, and a little later in birch.

The second sign of spring is the flowering of wind-pollinated trees and shrubs.

Gray alder is the first to bloom in the central European part of the USSR. Its flowers are inconspicuous, but the blooming earrings of staminate flowers are clearly visible 123 . As soon as you touch an alder branch with earrings, the wind picks up a whole cloud of yellow pollen.

Pistillate alder flowers are collected in small grayish-green inflorescences. Next to them, the dry, blackened cones of last year's inflorescences are usually clearly visible.

Almost simultaneously with the alder, the hazel tree, which you met in the fall, blooms.

The staminate flowers of hazel develop in inflorescences - complex catkins, and the reddish stigmas of pistillate flowers protrude from generative (flower) buds.

Early flowering of alder, hazel and other wind-pollinated plants plants - good fit to life in the forest.

Bare leafless branches do not impede pollination. Pollen picked up by the wind is freely transferred from one plant to another.

The flowering of coltsfoot is also a sign of the coming spring. This perennial herbaceous plant grows in open, sunlit places, on railway embankments, river banks, steep slopes and cliffs.

As soon as the snow melts, its scaly stems already appear - flower stalks with bright yellow inflorescences, similar to the inflorescences of dandelions 124 . Large leaves of coltsfoot grow after its fluffy fruits ripen and disperse.

Coltsfoot received its unusual name for the uniqueness of its leaves. Their underside is covered with white, soft, felt-like hairs, and the upper side of the leaves is smooth and cold.

Blooming coltsfoot in early spring, before the leaves bloom, perhaps because its thick, long rhizomes have accumulated reserves of nutrients deposited in the summer of last year.

Feeding on these reserves, flower plants grow shoots and fruits are formed.

The third sign of spring is the flowering of perennial herbaceous plants in the deciduous forest. In the areas middle zone they bloom almost simultaneously with the coltsfoot. The first to bloom in the forest are the noble liverwort with azure flowers and the lungwort, then the oak anemone and buttercup 125 , corydalis 119 , spring clear 126 , spring primrose 127 .

Flowering shrubs in spring

All of them are photophilous and bloom under the forest canopy, when there is no foliage on the trees and shrubs.

In the life of some early flowering herbaceous plants of the forest, their growth under snow is very interesting. Plants such as scilla or snowdrop grow under the snow in winter.

In the spring, many of them emerge from under the snow with green leaves and buds that formed last fall.

Οʜᴎ often bloom before the snow melts 128 . That's why these plants are called snowdrops.

Plants that bloom in early spring always attract attention because they are beautiful and because after a long winter they are the first flowering plants. Unfortunately, they are often collected in large bouquets. They often destroy entire plants by uprooting them. Plants whose flowering shoots are torn off do not produce fruits or seeds.

This makes it difficult for them to reproduce. Many of the plants have become very rare, for example, liverwort and sleep grass. We must not allow them to disappear completely. We are obliged to take care of the preservation of plants, not to tear them in order to throw them away every other day, not to damage them wild plants and actively protect nature.

Protection of Nature And rational use natural resources countries are legalized by the Constitution of Russia, i.e.

e. obligatory for all citizens of our country.

Trees and shrubs that are pollinated by insects bloom later, after the leaves have bloomed. If you observe the progress of spring from year to year, you will be able to establish the sequence of spring development of plants.

In the middle zone of the European part of the USSR, usually 8 days after the coltsfoot flowering, lungwort begins to bloom, and 21 days later - dandelion and willow willow.

The pear blooms on the 29th day, the yellow acacia on the 30th, and the linden on the 75th day after the coltsfoot begins to flower.

Every year, spring phenomena occur in strict order. For example, lungwort always blooms later than coltsfoot, but before dandelion.

Observations of spring phenomena in plant life help to establish best timing carrying out agricultural work and preparing for it in a timely manner.

For example, it is known: in areas of the middle zone best harvest cucumbers are obtained by sowing their seeds during the flowering of lilac and yellow acacia, and the best harvest of turnips and beets is obtained by sowing them during the flowering of aspen.

Knowing how many days after the flowering of the coltsfoot the lilac blooms, it is easy to set the date for sowing cucumbers and prepare for it.

Signs of spring in inanimate nature:
1) The main sign of spring in inanimate nature is that the sun rises much higher above the horizon than in winter.
2) It shines brighter and warms more and more every day.

The days are getting longer.
3) The most noticeable sign of the onset of spring in inanimate nature is the melting of snow.
4) The ice begins to melt. Ice drift begins on the rivers.
5) It is very dangerous to walk on melted ice. You cannot play games on the river during ice drift.
6) When rivers and lakes overflow with water from melted snow, water fills meadows, forests, and fields along the river.

This is called high water.
7) The soil thaws from the spring heat. A lot of moisture accumulates in it. Plants really need this moisture.
8) In spring it rains, not snow. The first thunderstorm is not far away.

Signs of spring in wildlife:
a) in the life of birds with the arrival of spring: migratory birds return, build nests, lay eggs, hatch chicks
Such changes became possible because many birds feed on insects. And with the arrival of spring, insects crawl out of their hiding places.

There is more food for the birds. Ice on rivers and lakes has melted, so waterfowl are returning

b) in the life of animals: Animals shed - they change winter coat for the summer. Bears, badgers, hedgehogs, and chipmunks are waking up from their winter sleep.

Many animals give birth to cubs in the spring.

c) Buds swell on deciduous trees and shrubs; catkins, silvery lambs, flowers appear, then leaves appear. U coniferous trees The color of the bark and needles changes.
Young grass covers the ground, many plants begin to bloom. Usually early flowering herbaceous plants They are called snowdrops.

if you write everything briefly:
The sun is higher than in winter. The days have become longer. It's getting warmer outside. The sky in spring is blue and high.

The clouds are white and light. Snow and ice are melting. There is ice drift and flood on the rivers. In the spring, it snows or rains in different months. In May the first thunderstorm thunders. The soil thaws, buds appear on the trees, and then sticky leaves appear. Primroses are blooming. Insects appear. Migratory birds are returning. Forest animals breed.

– familiarization with changes in trees and shrubs, with changes in buds.

Progress of the lesson:

– What is the name of the underground part of the mushroom?

– Do you need a fly agaric?

– Who is it useful for?

– What mushrooms cannot be picked?

– What should be done to avoid damaging the mycelium?

– Is it possible to collect old mushrooms?

1. Statement of the topic and purpose of the lesson.

It is impossible to imagine our nature without the white-trunked beauty of the birch. How many fairy tales, poems, songs have been written about her? Interestingly, the birch, the only tree in Russia with white bark, lives

birch 100 - 120 years. Yes, people love birch, but how often do they not take care of it? Losing a considerable part of its sap in the spring due to human fault, the birch

If you inflict wounds on her for several years in a row, she may

completely die. Remember that the sugar contained in the sap is needed to nourish the tree!

The movement of sap in trees and shrubs is a sign of their spring

awakening.

Another sign is the flowering of some trees and shrubs. Alder is the first tree to bloom. It is easily recognized in winter and spring by the black cones on the branches. In spring, catkins appear on alder trees.

Which trees are the first to wake up in spring? I urgently give 100 points

Earrings are many small flowers gathered together.

Willow blooms early in spring. Bees and bumblebees hover near its flowers. They come here for sweet nectar.

Of the shrubs, hazel and wolf's bast bloom the earliest. On hazel, like on alder, catkins are visible. And wolf's bast is a poisonous plant.

All these plants are early flowering. They bloom before they bloom

Birch blooms later, when its leaves are already beginning to bloom.

Even later, the bird cherry blossoms.
