MCQ
Deplasmolysis occurs when a plasmolysed cell is placed in:
- AConcentrated salt solution
- ✓Tap water
- CConcentrated sugar solution
- DHypertonic salt solution
✓
Answer
Correct option: B.
Tap water
(b) Tap water
Explanation:
Placing a plasmolysed cell in tap water, which is a hypotonic solution (less concentrated than the cell contents), will cause water to move into the cell by osmosis. This influx of water causes the cell to swell and return to its normal shape, a process known as deplasmolysis. The other options, being either hypertonic or similar in concentration to the plasmolysed cell's environment, would not lead to deplasmolysis.
