1、 What is it

Respiration is that the cells of plants absorb O2, and then oxidize and decompose gradually under the action of a series of enzymes, so as to convert organic matter into CO2 and water, and release energy. This is a very important step in the growth process and is of great significance to the growth activities of plants. Note that only living cells can be carried out, which is one of the needs of life. All organs of a living plant can be carried out as a whole, or even separated from the plant itself. As long as it is still a living cell or tissue, it can be carried out, but if the cell dies, it will not be able to carry out such activities

In a very oxygen rich environment, a lot of energy will be released, which can be supplied to plants again. If there is a lack of oxygen, only a small amount of energy can be released, and it will be decomposed into lactic acid or alcohol. This is a harmful substance, which is unfavorable to plant growth

2、 Meaning

1. Providing energy: the respiration of plants is mainly to provide energy for life. These energy can then act on the plant itself for a series of life activities such as cell division, plant growth, mineral element absorption and so on

2. Provide raw materials: some intermediate products may be produced during respiration, which can become raw materials for the synthesis of important compounds in the body
