Answer
Soln:
Answer is (b) shrinkage of cytoplasm in hypertonic medium
Explanation:
Living plant cell loses water through osmosis resulting in shrinkage or contraction of the contents of the cell away from the cell wall. This phenomenon is known as plasmolysis.
When plant cell has more water content than in the surrounding plant cell tend to transfer water to its surroundings which results in shrinkage of the cell through plasmolysis.
