Guard Cells

Explanation:
Detailed explanation-1: -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-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.
Detailed explanation-3: -Reason: The cause of the opening or closing of stomata is the change in the turgidity of the guard cells.
