NEET Biology question

Not in NEET syllabus

An RBC and a plant cell (with a thick cell wall) are placed in distilled water. The solute concentration is the same in both the cells. What changes would be observed in them?

(A)Both plant cell and RBC would not undergo any change
(B)The RBC would increase in size and burst, while the plant cell would remain about the same sizeCorrect
(C)The plant cell would increase in size and burst, while the RBC would remain about the same size
(D)Both plant cell and RBC would decrease in size and collapse

Answer: (B)

Solution

In distilled water (which is strongly hypotonic to both cells), water enters both cells by endosmosis. The RBC, having no rigid cell wall, keeps swelling until its plasma membrane ruptures and it bursts. The plant cell's rigid
