2. function of epidermal cells =it provide a protection to the plant from the external environment.
3. stomata is tiny opening or pores that enables gaseous exchange.
4. stomata are pores in the leaf that allow gas exchange. where water vapour leaves the plant and carbon dioxide enters. when the stomata open transpiration rates increase and when the stomata are closed transpiration rates decrease.

guard cells regulating transpiration. they are kidney shaped cells that protects the stomach and are responsible for opening and closing the pores of stomata
