How do stomata help in respiration
Answers
Answer:
Stomata are small pores on the surface of leaf. It has a pair of guard cells on the side which helps it to open and close the pores.
Taking in oxygen is very important because it allows your cells to do things, like make energy from the food you eat. Plants 'breathe' too, but they do it through tiny openings in leaves called stomata (singular: stoma). Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.
Stomata are small pores on the surface of leaves which help in respiration. Lenticels are the openings made due to the bark on the stem which help in exchange of gases through stem. Both of them help in exchange of gases in plants and trees
Stomata control gas exchange. When open, these pores allow carbon dioxide in, and oxygen and water out. Carbon dioxide in for carbon fixing. Oxygen out to avoid photorespiration.
Three functions of stomata.
1) It helps in the transpiration of water, i.e., the loss of excess water from the plant.
2)Loss of water from the stomata creates an upward pull, i.e., suction pull which helps in absorption of water from the roots.
3)Stomata are responsible for the interchange of gases for respiration and photosynthesis.
