If a plasmolysed plant cell is placed in water the cell will___________?
Correct answer: C. Be deplasmolysed
- A. Burst
- B. Be Killed
- C. Be deplasmolysed
- D. Show no change in it
Explanation
Water enters a plasmolysed plant cell by osmosis because the cell sap has a lower water potential than the surrounding water. The protoplast expands and the cell becomes deplasmolysed, while the cell wall prevents bursting under normal conditions. Students may choose a by assuming that water uptake always makes a plant cell burst, ignoring the support provided by the cell wall.
