The loss of turgor pressure in _______ results in closure of stomatal pore.
Open in App
Solution
The correct option is B guard cells
The opening and closing of the stomata are controlled by the guard cells. In the presence of light, guard cells take up water by osmosis and become turgid because of which their inner walls become rigid and they are pulled apart, opening the pore. In dark, the water is lost and the inner walls move together closing the pore.
