Why are falling tree leaves?

Why are trees falling?

Few are the wonders of nature that match trees' pomegranate, beauty and complexity. But it's better than just being a beautiful piece . It is a masterpiece of natural engineering that has evolved over millions of years, makes food for the plant it carries and provides food for all animals of the earth and for humans as well.

The leaves are the branching parts of the stem or leg, made up of the same fibers and tissues as the bud. The leaf is made up of a wide, contrasting green surface, tied to the leg with a small sweat. The outer surface of the paper is filled with a group of branching veins, which carry food to the tissues of the leaf, supporting them as well as supporting the ribs of the human body.

This process is known as the process of photosynthesis, which is the main key to the ability of the plant to produce food. All plants are made of chlorophyll, a green dye that absorbs sunlight and enables the plant to build carbohydrates from atmospheric carbon dioxide and water.

All these chemicals go to the interior of the paper, which is protected by a layer of plant skin, and is linked to the skin of the leg, which prevents the entry of any harmful element from the outside.

The internal piece of the leave contains soft cell walls . Consists of five chloroplasts containing chlorophyll that absorbs sunlight. These cells produce enzymes - the proteins produced by living cells - that are the catalysts in the chemical reaction on which the plant's life depends.

At the start of photosynthesis, these enzymes, in conjunction with the energy of the sun's rays, break down water into two important elements, hydrogen and oxygen. Oxygen from the photosynthesis process creates special gaps on the surface of the plant leaf, replacing the oxygen absorbed by the plant during the breathing process. At the same time, enzymes combine with hydrogen released from water and with carbon dioxide to be the carbohydrates that are the basis of plant and animal life and thus human. So, we can say that the chemical reaction that occurs inside the paper, a very vital element of life on Earth. Here we return to our original question about why leaves fell in autumn. This phenomenon occurs once a year in seasonal trees and every two or three years in permanent trees green.

You will find the answer to the question, priorities in the life of the paper. Although they play an active role in the world around them, their main duty is to support their mother tree, especially at some point of growth, when the tree is unable to absorb sufficient food from the soil. Although the process of sugar production continues the life of the plant, it is not very necessary in the growing stage.

Leaf falls in different tree species occur because of the weakness of the area that binds the leaves to the stem of the plant or bud. Nature takes its course. The leaves fall when the day is short and the process of photosynthesis is slowed down and the amount of light that reaches the leaves decreases. When this occurs, soft cells form across the base of the neck between the paper and the stem. The wound quickly heals because the soft cells break down the injured leg and prevent further loss of food, which is dangerous in the colder winter months when light and food are low.
