Question

Give an account on stomatal transpiration

Answer 1

hey mate here is ur answer......

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is atmosphere. Transpiration is essentially evaporation of water from plant leaves.

Transpiration that takes place bystomata is known as stomatal transpiration. The stomatal transpiration is dependent on normal opening and closing ofstomata. The stomatal opening is brought about by turgidity in the guard cells where unequal thickening in the walls cause the pore to open.

Answer 2

The lose of water through sonata in the form of water vapour is known as transpiration. Stomata in epidermis helps in transpiration
