mention the steps involved in respiration in plants

Respiration in Plants
Plants like other animals also respire. Plants also need energy. The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy.
This energy is used by the plant for carrying out its various life processes. Thus, Like other organisms, plants also respire for their survival. The respiration in plants differs from that of animals. In other words, in plants, each part can independently take in oxygen from air, utilize it to obtain energy, and give out carbon dioxide.

Respiration In Leaves
The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata.
This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata.

The photosynthesis reaction makes glucose and the respiration reaction break it down. In photosynthesis, the energy which goes into the reaction is light energy. In respiration, the energy which comes out is chemical energy.

Respiration in Roots
The roots of plants are under the ground but root cells also need oxygen to carry out respiration and release energy for their own use.
How Does Respiration Occur in Roots?
The roots of a plant take up air from the spaces between the soil particles. Root hairs are in contact with the air in the soil particles. Oxygen from the air in soil particles diffuse into root hair and reach all the cells of the root where it is utilised in respiration. Carbon dioxide produced in the cells of the root during respiration goes out through the same root hair by the process of diffusion.

If a potted plant is over watered for a long time, then the plant may ultimately die. This is because too much water expels all the air from in between the soil particles. Due to this, oxygen is not available to the roots for aerobic respiration. In this condition, the roots of plant respire anaerobically producing alcohol. This may kill the plant. Germinating seeds during early stage respire anaerobically because they have seed coat which does not allow the oxygen to enter through it.
if it help you then plz mark it as brainliest ans.......
Answer:
It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the energy that cells need to do work. When they don't get enough oxygen, the cells use anaerobic respiration, which doesn't require oxygen.
