Question

A cell with fully elastic wall is placed in hypertonic solution. What will not happen?

• A. Change in cell size and shape.
• B. The whole cell will shrink.
• C. Cytoplasm shrinks from the cell wall and undergoes plasmolysis.
• D. Decrease in cell size.

Answer 1

Answer: (C)

Cytoplasm shrinks from the cell wall and undergoes plasmolysis.

A hypertonic solution is a solution which contains more amount for dissolved salts i.e., the concentration of solute is more.

When a cell is placed in hypertonic solution since the solvent concentration is less, the solvent is exerted from the cell and the cell undergoes cytolysis.

The pressure inside the cell is high and the cell may undergo osmolysis.

Cytoplasm will not shrink but cell solvent will come out it is not plasmolysis because the only periphery of the cell is not affected. So it cannot undergo plasmolysis.

So the correct answer is 'Cytoplasm shrinks from the cell wall and undergoes plasmolysis'.
