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.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
