Vedclass · Answer

(B) The opening of stomata is primarily driven by the increase in the turgor pressure of the guard cells. When water enters the guard cells through the process of $Endosmosis$,they become turgid. Due to the presence of thick inner walls and thin outer walls,the turgid guard cells bulge outwards,causing the stomatal pore to open.
