Plasmolysis and Deplasmolysis
- The term Plasmolysis is defined as “the contraction of the protoplasm to form an undifferentiated mass within plants due to loss of water through exosmosis.”

- To begin with, the plasma membrane detaches itself from the cell. This stage is called incipient plasmolysis.
- The vacuole decreases in its size and finally becomes indistinguishable. This stage is called evident plasmolysis.
- If the evident plasmolysis continues, it will cause the death of the plant cell.
- The space created due to the shrinking of the protoplasm is occupied by the plasmolysis solution, which is a hypertonic solution.
- Plasmolysis is usually reversible
- When a plasmolysed cell is kept in a hypotonic solution, it will regain its original shape and this process is called deplasmolysis.
