Vedclass · Accepted Answer

$\psi_{w} = \psi_{s} + (\psi_{p})$ where $\psi_{p}$ is negative

Vedclass · Answer

(D) The water potential of a cell is given by the equation $\psi_{w} = \psi_{s} + \psi_{p}$.In a fully turgid cell,the pressure potential $(\psi_{p})$ is positive.However,in a plasmolysed cell,the protoplast shrinks away from the cell wall,resulting in a negative pressure potential $(\psi_{p} Therefore,the expression for the water potential of a plasmolysed cell is $\psi_{w} = \psi_{s} + \psi_{p}$,where $\psi_{p}$ is negative.

The correct expression for the water potential of a plasmolysed cell is:
