When plant cells are kept in hypertonic salt solution, they get
Options
(a) turgid
(b) deplasmolysed
(c) plasmolysed
(d) lysed
Correct Answer:
plasmolysed
Explanation:
Plasmolysis is the loss of water by osmosis from a plant cell to the extent that the cytoplasm shrinks away from the cell wall. This happens when the cell is placed in a hypertonic solution that has a higher solute concentration than that of the cell sap, i.e. solution has more negative water potential. Thus water will move from an area of high water potential to an area of low water potential.
