Question

When do plant cells undergo plasmolysis? 1 point (a) In hypotonic solution (b) In isotonic solution (c) In distilled water (d) In hypertonic solution

Answer 1

If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cell shrink and crumple.
