Vedclass · Answer

(B) When a plant cell is placed in a hypotonic solution,water enters the cell due to endosmosis,causing the protoplast to press against the cell wall. This pressure is called Turgor Pressure $(TP)$. The rigid cell wall exerts an equal and opposite pressure on the protoplast,known as Wall Pressure $(WP)$. When the cell becomes fully turgid,$TP = WP$. At this stage,the net movement of water becomes zero,meaning no further exchange of water takes place between the cell and its environment,establishing a state of equilibrium.
