Detailed explanation-1: -The opening and closing of stomatal pores is regulated by guard cells by increasing or decreasing the amount of water in them. When water enters the guard cells, they become turgid. This results in opening of stomata) pore. When water exits from the guard cells, they become flaccid.
Detailed explanation-2: -The opening and closing of stomata are controlled by specialized cells called guard cells. The turgor pressure in the guard cells controls the opening and closing of the guard cells. Stomatal pores open when guard cells enlarge as a result of water absorption and close when guard cells shrink.
Detailed explanation-3: -> The change in the turgidity of the guard cells causes their opening and closing. > The guard cells are responsible to regulate the rate of transpiration by opening and closing the stomata.
