What happens to the pressure potential if the plant cell is kept in hypertonic solution

Dear student,

The pressure potential will become zero if the plant cell is kept in hypertonic solution.
 When the plant cell is placed in hypertonic solution, the cell would get plasmolysed; entire cell sap moves from inside the cell to the outside in the solution, so the pressure potential would become zero.
Pressure potential is build up by the water present in the cell, which makes the cell turgid.

Regards.
