What properties of air the plant uses: the characteristics of the environment


From this article you can find out which propertiesair uses a plant. After all, most of the representatives of this realm of living nature have mastered the terrestrial habitat. It is inseparable from the air envelope, which means that without the air, plant life is simply impossible.

Composition of air

Very often the most necessary things, phenomena and processes are associated with the air. This means that the existence without it is simply impossible.

What is air?This substance is a natural mixture of gases. The greatest percentage of it is nitrogen. It occupies about 78%. This substance is necessary for normal development of the root system and a constant level of green pigments in plant chloroplasts. After all, the intensity of photosynthesis largely depends on the last parameter.

The second place in the percentage composition of air is oxygen. Its share is 21%. Without this gas, breathing and oxidation of organic substances are impossible, it supports the processes of combustion and decay.

Contained in the air and carbon dioxide.Its not so much - 0.03%. However, its role is important. Its presence is a necessary condition for photosynthesis to proceed. The rest of the air comes from inert gases, water vapor and impurities.

Air properties

To understand what properties of the air is usedplant, you need to understand the main characteristics of this mixture. It consists only of gaseous substances. By physical properties it is a homogeneous transparent mixture, the particles of which can not be visually discerned. The air is characterized by high heat conductivity, mobility, and the ability to conduct solar radiation. All these indicators act on plants in a complex manner.

Plants and air

Most plants live in land-to-airenvironment. In addition, algae that grow in water. Air can not support a certain position of organisms in space. Therefore, terrestrial plants, in contrast to algae, have well-developed mechanical tissues. Air is the environment for food, breathing and absorption of sunlight.

What properties of air does the plant use?

Through the air, plants perceive temperatureenvironment. In the process of evolution, they acquired certain adaptations to its fluctuations. So, with increasing this index, the intensity of transpiration - the evaporation of water from the surface of the plant - increases. As a result, organisms do not overheat. When the temperature is lowered, deciduous plants discard foliage, and in gymnosperm stomata the skin of the leaf is filled with resin.

Plants absorb oxygen from the air,necessary for breathing. Gas exchange also occurs through the structures of the leaf - the stomata, consisting of two valves and a gap between them. All plants are autotrophic organisms. This means that they are able to produce nutrients for themselves in the process of photosynthesis. And air plays an important role in this. From it, plants absorb carbon dioxide and solar energy. Only if they are present in the chloroplasts of the sheet will begin an amazing transformation of inorganic substances into glucose. A by-product of photosynthesis is oxygen, without which life is practically impossible.

Nitrogen is also necessary for plants.But in the gaseous state they are not able to assimilate this substance. This plant is helped by nitrogen-fixing bacteria that live on the roots of leguminous plants. They translate it into a soluble state. And plants suck it from the soil with the help of the root system.

So, what properties of air does the plant use?This chemical composition, as well as the ability to transmit heat and solar radiation. These properties of air make possible the growth and development of absolutely all plants of the planet, and hence, life on it.
