Vedclass · Answer

(C) When a plant cell is placed in pure water, water enters the cell due to endosmosis because the water potential of pure water is higher than that of the cell sap. As water enters, the cell becomes turgid and the pressure potential $(\Psi_p)$ increases. The process continues until the water potential $(\Psi_w)$ of the cell becomes equal to the water potential of the surrounding pure water (which is $0$). At this equilibrium, the pressure potential $(\Psi_p)$ of the cell becomes equal to its osmotic potential $(\Psi_s)$ in magnitude, resulting in a net water potential of $0$.
