Question

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:Q.23. Assertion: A cell swells up when present in a hypotonic solution. Reason: More water molecules enter the cell than they leave. *

option(a)-------- Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
option. (b) ------Assertion (A) is false, but reason (R) is true.
option. (c)------ Assertion (A) is true, but reason (R) is false.
option. (d)------ Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).​

Answer 1

Answer:

D) Both (A) and (R) are true, and (R) is the correct explanation of (A).

Answer 2

Answer:

Assertion (A) is false, but reason (R) is true.

Explanation:

The cell swells up when endosmosis occurs. Endosmosis is a process in which the water molecules move from outside to the inside of the cell through the cell membrane. This occurs when the solution is hypotonic, i.e., the cell has a lower solute concentration than the surrounding medium.
