Why are the leaves only green in spring? 5

The "only" should be removed, there is a tree whose leaves are red in the spring (not a little green), and the leaves turn green in the summer, this kind of tree is a very common urban greening tree.

I think the leaves change according to the air.

According to biology, green plants use light energy through chloroplasts to convert carbon dioxide and water into organic matter that stores energy. The chloroplasts of green plants use light energy to turn carbon dioxide into organic matter such as starch.

The leaves of green plants are generally green, flat, and spread out in the space, which is conducive to absorbing sunlight. Chloroplasts contain green chlorophyll, which is the main reason for the green color of leaves. Chloroplasts are the sites where green plants photosynthesize.

The leaves are green because of the chlorophyll in the leaves. However, in addition to green pigment, there are many pigments such as red pigment and yellow pigment in the leaves, but the amount is very small.

In spring and summer, chlorophyll is much more abundant in the leaves than other pigments, so the leaves show the green color of chlorophyll, and the color of the other pigments is not visible.

When autumn arrives, the days are shortened and the nights are lengthened, which causes the trees to begin to lose their leaves. Before the leaves fall, trees no longer produce large amounts of chlorophyll as they do in spring and summer, and existing pigments, such as chlorophyll, gradually break down. In this way, as the chlorophyll content gradually decreases, the colors of other pigments will gradually appear on the leaf surface, so that the leaves will show yellow, red and other colors.

We can see that almost all plants have green leaves, so why is it green?

The reason why the leaves are green

The leaves of the plant are green, which is the ability of the leaves of the plant to absorb various other visible light colors in the sun's rays, and only release green, so that people can only see green.

Sunlight is composed of red, orange, red, green, blue, blue, and purple light. Plants absorb six of these rays for photosynthesis in the plant's body, absorbing the energy of sunlight to make water and carbon dioxide synthesize carbohydrates and release oxygen at the same time. This is an important process that produces carbohydrates and oxygen in a continuous manner.

Most terrestrial and aquatic plants are green, but there are also red, yellow, etc. The green color of green plants is due to the fact that they contain a lot of chlorophyll in their leaves and stems. Plants rely on chlorophyll to process the water sucked by roots and the carbon dioxide breathed by leaves into starch and oxygen under ultraviolet irradiation in the sun, and the oxygen is put into the air, and the starch is transported to all parts of the plant to maintain the energy demand of plant growth.

The leaves of plants that contain more chlorophyll in the cytoplasm contain a lot of pigments, and the most of them in the leaves is green, which is the pigment that absorbs light energy, mainly absorbs red light and blue-violet light, and absorbs the least green light, so the green light is reflected out, and the leaves are green.

Spring is green because, it represents hope. Spring is blue because of the blue sky. Spring is green and drained, look at the thread of wicker. Spring is purple, look at the beautiful cloud flowers.

Spring is white, look at the white pear blossoms. Spring is fragrant yellow, look at the beautiful spring flowers. Spring is colorful because it is the season of revival of all things, full of color and vitality everywhere.

In fact, everything in nature is beautiful. This includes winds, torrential rains, sandstorms, but also **, tsunamis and even plagues. It's just that our preferences are selective, and our genes dictate it.

Lichun:

From the beginning of the spring solar term, the sky has only entered the spring. The most striking feature of the beginning of spring, in nature, is that all things begin to show signs of recovery. When it comes to the beginning of spring, in our country, the Tropic of Cancer and the area south of it, you can clearly feel the breath of early spring.

And in most areas to the north, it can only be said that it is the prelude to spring, when everything has not yet recovered, and it is still in the winter when everything is closed. For areas north of the Tropic of Capricorn, the farther away from the Tropic of Cancer (Yellow-Red Junction), the later spring begins.

Spring is usually defined as March and May in the Northern Hemisphere, while spring is defined as late September and late December in the Southern Hemisphere. In modern meteorology, spring begins when the average temperature is above 10 for 5 consecutive days.

The leaves of the trees are green all year round and are evergreen trees, which are divided into evergreen trees and evergreen shrubs.

These trees are evergreen all year round because they don't have a distinct defoliation season, and the leaves can be on the branches for 12 months or more. But this does not mean that they do not lose their leaves, in fact, they have fallen leaves all year round, but at the same time as the leaves fall, new green leaves also grow, and it seems that they are evergreen all year round.

The opposite is deciduous trees, which have completely lost their leaves at some point throughout the year and their branches become bare and leafless.
