Vedclass · Answer

(D) Photonasty is a nastic movement of a plant part in response to light. Sleep movements (nyctinasty) in plants like $Mimosa$ $pudica$ or $Oxalis$ are primarily caused by changes in turgor pressure in the cells of the pulvinus (the swollen base of the leaf). These movements are triggered by changes in light intensity (photonasty) or temperature (thermonasty). Therefore,the movement is a result of differential turgor changes or differential growth/activity at the base of the leaf (pulvinus).

Sleep movements of leaves in certain plants or photonasty is due to:
