The importance of plants in nature


What is the significance of plants in nature</a>

Thanks to photosynthesis, green plants play a very important role in life on Earth.

They convert the energy of sunlight and accumulate it in the form of organic compounds.

As a by-product of photosynthesis, oxygen is released into the atmosphere.

Life on the planet depends on the Sun. Photosynthetic green leaves of plants perceive and accumulate energy of sun rays.

What is photosynthesis

Photosynthesis is the process of creating onLight organic substances from inorganic. During this process, solar energy is converted into energy of chemical bonds. Carbohydrates, proteins and fats, stored in the cells of green plants, ensure the vital activity of all living things on Earth.

Sugar is the main product of photosynthesis

The most important product of photosynthesis isSugar, produced in nature by billions of tons annually. In starch and various sugars contains a lot of energy. Thus, in the accumulation of the organic mass and the storage of energy contained in organic substances, the main function of plants in nature consists.
Constant absorption and accumulation of energySolar radiation by green plants increases the overall level of energy in the biosphere. Energy, once stored in plant cells, is actively used by man in the burning of wood, oil, gas and coal.

A by-product of photosynthesis is oxygen

Oxygen - a by-product of photosynthesis -Currently occupies 21% of the air volume. Every year it enters the atmosphere in the amount of 70-120 billion tons. Thanks to this, animals (including humans), bacteria, fungi and plants can breathe and carry out life processes.
At an altitude of 25 km above the Earth's surface,Oxygen under the influence of solar radiation formed ozone. The ozone screen delays those ultraviolet rays that are capable of destroying living cells and have a harmful effect on organisms.

The level of carbon dioxide in the Earth's atmosphere

0.03% of the air volume in the Earth's atmosphereIs carbon dioxide. It is formed in the process of breathing, when decaying and decomposing dead bodies, during fires, volcanic eruptions, and fuel combustion. A huge amount of carbon dioxide is absorbed by green plants, so that the level of CO2 in the Earth's atmosphere remains constant.

Soil Formation

Living beings consume organic substancesGreen plants. Wastes of their vital activity fall on the earth's surface, decompose and form the soil. Its fertility depends on the content in the soil of organic substances - humus.
