Vedclass · Answer

(A) The shrinkage of the protoplast of a living cell away from its cell wall due to exosmosis under the influence of a hypertonic solution is called Plasmolysis.When a cell is plasmolysed,it loses water and becomes flaccid.In a flaccid cell,the turgor pressure $(TP)$ becomes zero.Since the diffusion pressure deficit $(DPD)$ is calculated as $DPD = OP - TP$,when $TP = 0$,the $DPD$ becomes equal to the osmotic pressure $(OP)$.
