Question:
When a few plasmolysed cells are kept in ____________ solution, the cells become turgid.
When a few plasmolysed cells are kept in ____________ solution, the cells become turgid.
Show Hint
Water enters a cell when the outside solution has higher water potential than the cell sap.
Updated On: Nov 12, 2026
- hypertonic
- hypotonic
- isotonic
- 20% sugar
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
A cell becomes plasmolysed when water leaves it in a hypertonic solution and the protoplast shrinks away from the wall.
Step 2: Reverse the process
In a hypotonic solution the outside water potential is higher than that of the cell sap, so water enters by endosmosis.
The protoplast swells back and presses on the wall, so turgor pressure develops (deplasmolysis).
Step 3: Conclusion
Plasmolysed cells become turgid in a hypotonic solution.
Final Answer:
A hypotonic solution makes plasmolysed cells turgid. \[ \boxed{\text{(B) }\text{hypotonic}} \]
