Question

A RBC and a plant cell having same O.P. are placed in distilled water, then

• A. None undergoes any change.
• B. Plant cell swells up and bursts but plant cell remains about the same size.
• C. RBC swells up and bursts but there is no change in plant cell.
• D. Both decrease in size and collapse.

Answer 1

Answer: (C)

RBC swells up and bursts but there is no change in plant cell.

Distilled water is a hypotonic solution contained within the red blood cell membranes that is why distilled water will diffuse into the red blood cells and cause them to burst.

So, the correct answer is 'RBC swells up and burst but there is no change in the plant cell'.
