Increased turgidity of the guard cells brought about by exposure to light

Vedclass · Answer

(B) The opening and closing of stomata are primarily regulated by the turgor pressure of the guard cells. When guard cells are exposed to light,they actively accumulate potassium ions $(K^+)$,which lowers their water potential. This causes water to enter the guard cells via osmosis,leading to an increase in their turgidity. Due to the specific arrangement of cellulose microfibrils in the guard cell walls,this increased turgor pressure causes the guard cells to bow outwards,thereby opening the stomatal pore.
