Question

what are stomata? how do they help in process of respiration?

Answer 1

Dear student,
Stomata are tiny pores present mainly on the surface of leaves. They are also present on the surface of young stems and roots.Stomata consist of a stomatal opening or stoma, which is surrounded by two distinct epidermal cells known as guard cells.
Stomata plays an important role during the process of respiration. Exchange of gases occurs through stomata i.e. during respiration, oxygen enters the plant through stomata and carbon dioxide which is the byproduct of respiration is also released through it.
