Question

Blood cells when kept in a liquid start shrinking. What type of a solution might it be?

• A. Hypotonic solution
• B. Hypertonic Solution
• C. Isotonic solution
• D. None of the above

Answer 1

The correct option is B

Hypertonic Solution

The correct option is B:
Explanation of correct option-

1. Hypertonic solution is a type of solution in which solute concentration is more and water concentration is less.
2. When red blood cell is placed in this solution, water leaves the cell leading to the shrinking of the cell.
3. The movement of water from the region of higher concentration to the region of the lower concentration is called osmosis.

Explanation of incorrect option-

Option A-

1. Hypotonic solution is a type of solution in which water concentration is more and solute concentration is less.
2. When red blood cell is placed in this solution, water enters the cell leading the cell to become turgid.

Option C-

1. If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable.

Option D- None of the above

Final answer: Blood cells when kept in a liquid start shrinking. The solution will be hypertonic solution
