Vedclass · Answer

(A) Water potential $(\Psi_w)$ is a measure of the potential energy of water in a system compared to pure water. It is expressed in units of pressure because it represents the chemical potential of water. The standard $SI$ unit for pressure is the Pascal $(Pa)$. Therefore, water potential is commonly measured in units such as $Pa$, $kPa$, or $MPa$.
