The cosmic role of plants: what is it?

The cosmic role of plants has long been proven by many scientists. A special role in the study of this process was played by the Russian researcher Kliment Timiryazev. It was he who proved that this process is of vital importance. On what features of the structure is this unique property of plant organisms based?

The cosmic role of green plants

All living organisms are characterized by certain signs. However, they all need oxygen to carry out the breathing process. The cosmic role of plants is to provide all organisms with this vital substance. Only plants are capable of producing it in the course of a unique process called photosynthesis.

Representatives of plants: characteristic features of the structure

Why do other organisms not produce oxygen in the process of their life? Because only plants have unique features of the structure. First of all, this is the presence in the cell of green plastids of chloroplasts. On the inner surface of these organelles is the process of photosynthesis, which determines the cosmic role of plants. Characteristic features of representatives of this realm of living nature is also the presence of cellulose carbohydrate in the cell wall. This substance gives the surface unit strength and rigidity. As a reserve nutrient in the cytoplasm of cells, starch granules are deposited. This polysaccharide is formed from numerous glucose molecules synthesized in the process of photosynthesis. Unlimited growth is also characteristic of plants. This means that the process of quantitative changes in them occurs throughout life.

The essence of the process of photosynthesis

So, the cosmic role of plants is manifested in the course of photosynthesis. The very name of this process indicates the participation of solar radiation in it. And indeed, photosynthesis consists in the formation of organic substances from mineral substances, provided that there are quanta of light. It occurs only in green plastids of chloroplasts. On their inner surface carbon dioxide interacts with water. The products of this unique chemical reaction are glucose monosaccharide and oxygen. The first substance of a plant is used as an energy source for the realization of vital processes. And oxygen participates in the respiration processes of absolutely all living organisms.

Conditions for the passage of photosynthesis

Synthesis of organic substances and oxygen, which is the cosmic role of plants on earth, is possible only in the presence of sunlight. Scientists have proved that the intensity of photosynthesis depends on its amount. It increases to an illumination of 15 thousand lux, and then goes to a decline. In autumn, there is a natural decrease in the amount of sunlight. As a result, the leaves change color and fall off. The essence of this process is the conversion of green plastids into yellow and purple, which are called chromoplasts. At the same time, the sheet can no longer perform its functions and ceases to be vital. Leaf fall is of protective importance for plants in the cold period, because this process practically stops transpiration. After all, it is very unreasonable to lose moisture during the period of its lack.

Solar radiation is necessary only in the first phase of photosynthesis. It is called light. During this period, energy is accumulated to trigger a complex chemical reaction and activation of chlorophyll. After that, the light is no longer needed. There comes a dark phase, during which there is an accumulation of carbohydrates. Also, the necessary conditions for the passage of photosynthesis is the presence of water and carbon dioxide.

Photosynthesis: the cosmic role of plants

Plants exercise an amazing cycle. They release oxygen, all living organisms use this substance to oxidize organic substances, resulting in the release of carbon dioxide. It is he who is a necessary condition and reagent in the process of photosynthesis. Only plants are capable of this. By type of food, they are autotrophs capable of producing organic substances independently. The cosmic role of green plants is to provide the necessary conditions for the life of living organisms. Moreover, if it is traditionally believed that it is the forests that are the "lungs of the planet," then in fact a huge part of the oxygen produced on the planet is accounted for by the share of aquatic plants.

So, the cosmic role of plants is in the process of photosynthesis. In its course in plastids, chloroplasts, in the presence of water and carbon dioxide, there is a magical appearance of glucose and oxygen, necessary for the breathing of all living organisms that live in the biosphere.
