1.	Question : Define the terms 'plasmolysis' and 'deplasmolysis'.
Answer» Solution :The phenomenon of shrinkage of protoplast from the cell wall due to EXOSMOSIS in a plant cell when placed in a hypertonic solution is called plasmolysis. When a plasmolysed cell is IMMEDIATELY placed in a hypotonic solution, the protoplast swells up due to gain of water and comes in CONTACT with the cell wall. This process is called DEPLASMOLYSIS.
