From our article you can find out what properties of air a plant uses. After all, most representatives of this kingdom of wildlife have mastered exactly the terrestrial habitat. It is inseparable from the air envelope, which means that without air the life of plants is simply impossible.
Air composition
Very often the most necessary things, phenomena and processes are associated with air. This means that existence without it is simply impossible.
What is air? This substance is a natural mixture of gases. The highest percentage in it belongs to nitrogen. It occupies about 78%. This substance is necessary for the normal development of the root system and a constant level of green pigments in plant chloroplasts. Indeed, the intensity of photosynthesis largely depends on the latter indicator.
The second place in the percentage of air is oxygen. Its share is 21%. Without this gas, breathing and oxidation of organic substances is impossible, it supports the processes of combustion and decay.
Contained in the air and carbon dioxide. It is not so much - 0.03%. However, his role is important. Its presence is a necessary condition for the occurrence of photosynthesis. The rest of the air is inert gases, water vapor and impurities.
Air properties
To understand what properties of air a plant uses, you need to understand the main characteristics of this mixture. It consists only of gaseous substances. According to its physical properties, it is a homogeneous transparent mixture, the particles of which cannot be visually distinguished. Air is characterized by high thermal conductivity, mobility, and the ability to conduct solar radiation. All these indicators act on plants comprehensively.
Plants and air
Most plants live in a land-air environment. In addition, algae growing in water. Air is not able to maintain a certain position of organisms in space. Therefore, terrestrial plants, unlike algae, have well-developed mechanical tissues. Air is a medium for nourishment, respiration and absorption of sunlight.
What properties of air does the plant use?
Plants perceive ambient temperature through air. In the process of evolution, they acquired certain adaptations to its vibrations. So, with an increase in this indicator, the intensity of transpiration increases - evaporation of water from the surface of the plant. As a result, organisms do not overheat. With a decrease in temperature, deciduous plants drop foliage, and in gymnosperms the stomata of the leaf skin are filled with resin.
Plants absorb oxygen from the air for breathing. Gas exchange also occurs through the structure of the leaf - 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 also plays an important role in this. From it, plants absorb carbon dioxide and solar energy. Only when they are present in the leaf chloroplasts will the surprising conversion of inorganic substances into glucose begin. A by-product of photosynthesis is oxygen, without which life is almost impossible.
Nitrogen is also needed by plants. But in a gaseous state, they are not able to absorb this substance. Nitrogen-fixing bacteria that live on the roots of legumes help this plant. They translate it into a soluble state. And plants absorb it from the soil using the root system.
So, what are the properties of air used by the plant? This chemical composition, as well as the ability to transfer heat and solar radiation. These properties of air make possible the growth and development of absolutely all plants on the planet, and therefore life on it.
