Vedclass · Answer

(D) Water potential $(\psi)$ is a measure of the free energy of water per unit volume. It is a pressure unit.$1$ bar is approximately equal to $14.5$ $lb/in^2$, $750$ $mm$ of $Hg$, and $0.987$ $atm$.Since all these units are used to express pressure, water potential can be measured in any of these units.Therefore, the correct option is $(d)$.

Water potential $\psi$ is measured in bar or in:
