With reference to water potential of a plant cell, the relationship is represented by

$ψ_{w} = ψ_{m} + ψ_{s} + ψ_{p}$

$ψ_{w} = ψ_{m} - ψ_{s} - ψ_{p}$

$ψ_{w} = ψ_{m} - ψ_{s} + ψ_{p}$

$ψ_{w} = ψ_{m} + ψ_{s} - ψ_{p}$

Solution

$ψ_{w} = ψ_{m} + ψ_{s} + ψ_{p}$

The difference between the free energy of water molecule in pure water and the energy of water in any other system is termed as water potential. Movement of water occurs from region of high water potential to low potential i.e.

$ψ_{w} = ψ_{m} + ψ_{s} + ψ_{p}$

Here, $ψ_{w}$ = water potential; $ψ_{m}$ = metric potential; $ψ_{s}$ = solute potential; $ψ_{p}$ = pressure potential
