Explanation:
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: -Two highly specialized cells, the guard cells that surround the stomatal pore, are able to integrate environmental and endogenous signals in order to control the stomatal aperture and thereby the gas exchange.
