Summary Introduction

To review:

The function of solute potential and pressure potential in water potential.

Introduction:

Solute potential or osmotic potential is denoted by (ѱ_s). It is negative in a plant cell and zero in distilled water. The turgor potential, also called pressure potential, is denoted by (ѱ_p). It may be positive or negative. The water potential can be calculated as $\text{ψ}={\text{ψ}}_{\left(\text{p}\right)}+{\text{ψ}}_{\left(\text{s}\right)}$.
