Respiration is that the cells of the plant absorb O2, and then gradually oxidize and decompose under the action of a series of enzymes, so as to convert the organic matter into CO2 and water, and also release energy, which is a very important step in the growth process, and is of great significance for the growth activities of the plant. Note that only living cells can be carried out, which is one of the needs of life. All the organs of living plants can be carried out, even separated from the plant itself, as long as the living cells or tissues can still be carried out, but if the cells die, they will not be able to carry out such activities.
In an environment with sufficient oxygen, a lot of energy will be released, which can be supplied to plants again. If the lack of oxygen, only a small amount of energy can be released, it will decompose into lactic acid or alcohol, which is harmful to plant growth.
1. Provide energy: plants breathe, mainly to provide energy for life. These energy can be used in plants, such as cell division, plant growth, mineral element absorption and a series of life activities.
2. Provide raw materials: some intermediate products may be produced in the process of respiration, which can be used as raw materials for the synthesis of important compounds in vivo.
