Question

An unripe mango placed in a concentrated salt solution to prepare pickle, shrivels because-

• A. It gains water due to osmosis.
• B. It loses water due to osmosis.
• C. It gains water due to reverse osmosis.
• D. It loses water due to reverse osmosis.

Hint:

Cells placed in a hypertonic solution lose water by osmosis and shrink. This principle is applied in food preservation methods like pickling.

Answer 1

The Correct Option is B

Step 1: The concentrated salt solution is hypertonic compared to the cell sap of the mango.
Step 2: Due to osmosis, water moves from a region of higher water concentration (inside the mango cells) to a region of lower water concentration (salt solution).
Step 3: Loss of water from the cells causes them to shrink, resulting in the shrivelling of the mango.
