In spring, the trees wake up and begin to turn green. In some plants, they are huge.

For example, in royal Victoria’s water, the leaf looks like a large dish floating on water.

Such a sheet can even support the weight of a small child. Many leaves serve as excellent food for humans.

Suffice it to recall the salad, savoy cabbage and other herbs that we eat. The leaves of plants differ from each other in shape and size.

Inside sheet

It looks like a piece of sheet, enlarged several hundred times. There are small holes in it so that the sheet can breathe, just like people inhale air containing oxygen with their noses. But the leaves of plants can absorb carbon dioxide during the day, releasing oxygen into the air, and at night oxygen is not released. Thus, plants bring a lot of benefits to a person - they purify the air of carbon dioxide and produce a lot of oxygen. Therefore, forests are called the "lungs" of the Earth.

Chemical laboratories

Plant roots absorb moisture and mineral salts from the soil, and leaves absorb carbon dioxide from the air. These substances feed on plants. But in order to assimilate them, plants need sunlight. This produces oxygen, which is released into the air. As in a small laboratory, leaves consume carbon dioxide and produce oxygen.

Why do the leaves turn yellow

In autumn, before dropping the leaves, the plant fills them with unnecessary substances accumulated in it over the long summer months.In more detail, why the leaves turn yellow in autumn is written here.
