What is plasmolysis? What will happen to a plasmolysed cell when it is placed in water?

Plasmolysis is the process that takes place when the plant cell losses cytoplasmic water due to osmosis and shrinks in size.

It occurs when the plant's cell is placed in a hypertonic solution or solution having a higher concentration of salts. Cytoplasm loses its water to the hypertonic solution to achieve equilibrium and shrinks.

When a plasmolysed cell (or the cells whose cytoplasm got shrunk) is placed in water, the cell absorbs water from the surrounding due to varied concentration gradient and tries to regain its original size and shape. Thus, the plant cell becomes turgid.
