When a living plant cell is placed in a strongly hypertonic solution, the protoplasm shrinks and pulls away from the cell wall. This shrinkage is known as what?
ATranspiration
BImbibition
CGuttation
DPlasmolysis
Answer & Solution
Correct answer: D. Plasmolysis
1. In a hypertonic solution, water leaves the cell by osmosis.
2. Loss of water makes the protoplasm shrink away from the wall.
3. Guttation and transpiration are water-loss outputs, not protoplasm shrinkage, ruling out options A and C.
4. The named shrinkage is plasmolysis, option D.
