The phenomenon of shrinkage of protoplasm from the cell wall of the plant cell under the influence of a hypertonic solution is called plasmolysis. Incipient plasmolysis is the beginning phase followed by making the cell plasmolysed. If the plasmolysed cell is kept in a hypotonic solution, deplasmolysis takes place due to inflow of water or endosmosis.
