Question

When concentration of solute is low in plant cell, absorption of water is

• A. Retarded
• B. Increased
• C. Normal
• D. Absent

Answer 1

Answer: (A)

Retarded

The migration of water molecules plays an crucial role in the intake of water by cells across the semipermeable membrane. The process exosmosis takes place when the concentration of solute is low in plant cell as compared to the surrounding solution. As a result of this plasmolysis occurs causing movement of water particles out of the cell and shrinking of the cell membrane away from the cell wall when placed in low osmotic concentration of cell sap compared to the outer solution.

So, the correct answer is option A.
