Question:
Assertion (A): Blood cells collapse when suspended in saline water
Reason (R): Cell membrane dissolves in saline water
Assertion (A): Blood cells collapse when suspended in saline water
Reason (R): Cell membrane dissolves in saline water
Reason (R): Cell membrane dissolves in saline water
Show Hint

- Both (A) and (R) are correct and R is the correct explanation of A
- Both (A) and (R) are correct, but R is not the correct explanation of A
- (A) is correct but (R) is not correct
- (A) is incorrect but (R) is correct

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Blood cells collapse in saline due to osmosis. Hypertonic saline causes water to leave the cells, shrinking them.
However, the reason given that the membrane dissolves is incorrect. The membrane remains intact but loses water content.
