what are stomata? draw a labelled diagram of stomata & write two function of stomata.

Dear student

Above diagram is of stomata where A is the guard cell which closes and open the stomatal pore and B is the stomatal pore or stomawhich opens or closes depending on conditions.
For functions please refer below:-

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. The opposing inner walls of the guard cells are thick and inelastic. The remaining walls are thin and elastic.

The main functions of stomata are:

1. Exchange of gases (for photosynthesis and respiration)

2. Transpiration (Removal of water from leaf surface)

 stomata are the tiny pores present in the leaves (lower epidermis) which helps in gaseous exchange.

functions of stomata are-

1. helps in gaseous exchange that is respiration.

2.helps in photosynthesis.

3.they remain closed during night due to the loss of water by transpiration.
