Vedclass · Answer

(A) Water potential $(\Psi_{w})$ is the measure of the potential energy of water in a system compared to pure water. It determines the direction of water movement.The total water potential of a plant cell is the sum of its components: solute potential $(\Psi_{s})$,pressure potential $(\Psi_{p})$,and matric potential $(\Psi_{m})$.The standard equation is given by: $\Psi_{w} = \Psi_{s} + \Psi_{p} + \Psi_{m}$.Since $\Psi_{s}$ is always negative,the equation is often written as $\Psi_{w} = \Psi_{m} + \Psi_{s} + \Psi_{p}$.

Identify the correct relationship with reference to water potential of a plant cell.
