It is equal to zero when the cell is fully turgid in pure water.

Vedclass · Answer

(C) The water potential $(\Psi_w)$ of pure water at standard temperature and pressure is defined as $0$. When a plant cell is placed in pure water, water enters the cell due to osmosis, causing the cell to become turgid. As the cell becomes fully turgid, the solute potential $(\Psi_s)$ is balanced by the pressure potential $(\Psi_p)$, and the net water potential $(\Psi_w = \Psi_s + \Psi_p)$ of the cell becomes $0$. Therefore, the correct statement is that water potential is zero when the cell is fully turgid in pure water.
