Plasmolysis is important as it helps the plant by shrinking the protoplasm thereby controlling the plant from wilting. Since a plasmolysed cell can undergo deplasmolysis by placing the cell in the hypotonic solution so that the cell become normal. The phenomenon of plasmolysis is exploited in the process like salting of fish, adding the concentrated solutions of sugar to check the growth of the microorganism like bacteria, fungi etc.
