Assertion: Human RBCs burst in hypotonic solution.
Reason: Cells burst due to endosmosis.
The correct answer is option A, which states that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.
Explanation:
1. Hypotonic Solution:
- A hypotonic solution is one in which the solute concentration is lower outside the cell compared to the solute concentration inside the cell.
- In other words, the solution has a lower osmotic pressure than the cell.
2. Assertion: Human RBCs burst in hypotonic solution:
- The assertion states that human red blood cells (RBCs) burst in a hypotonic solution.
- This is indeed true.
3. Reason: Cells burst due to endosmosis:
- The reason provided is that cells burst due to endosmosis.
- Endosmosis is the process by which water molecules move into the cell through its selectively permeable membrane, causing the cell to swell and potentially burst.
4. Explanation of the Assertion and Reason:
- When a human RBC is placed in a hypotonic solution, the concentration of solutes inside the cell is higher compared to the concentration of solutes outside the cell.
- As a result, water molecules move from the hypotonic solution into the RBC through osmosis.
- The movement of water into the cell causes the cell to swell, and if the influx of water is significant, it can lead to the bursting of the RBC.
- This process is known as hemolysis.
5. Conclusion:
- The assertion that human RBCs burst in a hypotonic solution is true.
- The reason provided, which states that cells burst due to endosmosis, is the correct explanation for the assertion.
Therefore, the correct answer is option A.
