During a laboratory experiment, a student immerses epidermal leaf peel in a hypertonic solution. After some time, the student examined the cells under a microscope and observed that:
- A. the cells swelled.
- B. the cells were plasmolysed. ✓
- C. the cells built up turgor pressure.
- D. the cells size was unaffected.
Correct Answer: B. the cells were plasmolysed.
Explanation
In a hypertonic solution, the external concentration of solutes is higher than inside the cell, causing water to flow out (exosmosis), leading to plasmolysis of the cell.
