Question

A cell kept in a solution shrinks in size and loses its shape. The solution is :

• A. Hyper tonic
• B. Hypo tonic
• C. Iso tonic
• D. Pond water

Answer 1

The correct option is A

Hyper tonic

Correct option is A.

Explanation of the correct option:

1. In hypertonic solution, concentration of solute is more than solvent.
2. When a cell is kept in such type of solution it loses water and get shrink due to ex- osmosis.

Explanation of the incorrect options:

Option B:

1. In hypotonic solution concentration of solvent is more than solute.
2. So, water gets inside the cell and cell gets swell due to end osmosis.

Option C:

1. In isotonic solution concentration of both sides are equal.
2. So, cell retain in its shape.

Option D:

1. Pond water is also hypotonic to the cell .

Final answer : A cell kept in a hypertonic solution shrinks in size and loses its shape.
