If a plant cell is placed in hypertonic solution, plasmolysis occurs. As a result protoplast is reduced in size. This decreases turgor pressure. In a completely plasmolysed cell turgor pressure is zero. If the external solution does not cause any further exosmosis then, DPD = OP.

Q. For a plasmolysed cell which equation is correct?

DPD = OP + TP

DPD = -TP

DPD = OP

DPD = OP - TP.
