The forest air is pure and fresh thanks to the action of the leaves

Photosynthesis in leaves is the main reason forest air is clean and fresh.

Photosynthesis refers to the process by which plants use light energy to convert carbon dioxide and water into organic matter. During this process, plants absorb carbon dioxide and release oxygen. Therefore, forest trees continually release oxygen through photosynthesis, making the forest air richer in oxygen and absorbing a large amount of carbon dioxide.

Forest trees can also absorb some harmful gases, such as sulfur dioxide, nitrogen oxides, etc., and purify the air. The tiny pores on the leaf surface are stomata capable of absorbing moisture and gases from the air. Some harmful gases will be absorbed by the leaves and transformed into harmless substances.

The reason whyThe clean and fresh forest air is mainly because the leaves carry out photosynthesis and absorb harmful gases. This is one of the reasons why protecting forests and vegetation is important to improve air quality and protect the environment.

Organic substances produced by green leaves under light:

1. Glucose: It is an important monosaccharide, one of the main products of photosynthesis and the main component of plants and other organisms. . One of the sources of energy.

2. Starch: It is one of the main forms of energy storage in plants. It is a polysaccharide composed of several glucose molecules.

3. Sucrose: It is a disaccharide composed of glucose and fructose. It is another form of energy storage in plants and a signaling molecule in plants.

4. Amino acid: It is the basic unit of proteins et an important organic substance in plants.

5. Fatty acid: It is the basic unit of fat and an important organic substance in plants.

Necessary conditions for green plants to produce organic matter

1 Light energy: photosynthesis is a process that uses light energy for convert into chemical energy. Green plants need light energy to carry out photosynthesis. This is why green plants generally grow in sunny environments.

2. Chlorophyll: Chlorophyll is a green pigment that can absorb light energy and convert it into chemical energy. Green plants therefore need chlorophyll to carry out photosynthesis.

3. Carbon dioxide, water: Carbon dioxide is one of the raw materials of photosynthesis. Green plants need to absorb carbon dioxide from the air to rcarry out photosynthesis. Water is also one of the raw materials for photosynthesis. Green plants must absorb water from the soil or other water sources to carry out photosynthesis.

All green plants must be exposed to light to carry out photosynthesis. Water is an essential raw material for photosynthesis, and water is the basis for maintaining plant life.

Photosynthesis carried out by plants fundamentally determines the composition of the Earth's atmosphere. Without light and water, this means plants cannot photosynthesize, which means they cannot produce oxygen, which is harmful to all animals and plants. . All this is suddenly fatal.

Various plant organs and tissues can maintain normal developmental proportions and are directly related to a certain light intensity.

Nutrients needed by plants aremainly produced by photosynthesis. Plants contain chlorophyll, and water and air are the raw materials for photosynthesis.

Most of the water absorbed by plants evaporates from the leaves into the air, creating transpiration.

This traction force is the main driving force for roots to absorb water and mineral nutrients and to conduct minerals within the plant.

Plants can also regulate leaf surface temperature by absorbing heat through evaporation, so that leaves are not burned due to excessive temperature.
