A plasmolysed cell can be deplasmolysed by placing it in

A

pure water or hypotonic solution

B

hypertonic solution

C

isotonic solution

D

saturated solution.

Text Solution

Verified by Experts

The correct Answer is:
A
the swelling up of a plasmolysed protoplast under the influence of hypotonic solution or water is called deplasmolysis It is due to endosmosis Deplasmolysis is possible only immediately after plasmolysis otherwise the cell protoplast becomes permanently damaged. During deplasmolysis water diffuses into protoplast.
