उत्तर
| Plasmolysis | deplasmolysis |
| When a cell is placed in hypertonic solution , water begins to pass out of the cell by osmosis with a consequent shrinkage of protoplasm . This phenomenon is called plasmolysis . | When a plasmolysed cell is placed in hypotonic solution or pure water , endosmosis takes place as a result of which water is reabsorbed by the protoplast of the cell and it regains its original position . This phenomenon is called deplasmolysis . |
