Question

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

Answer 1

Correct Answer - B
When RBCs and a plant cell are placed in distilled water, endomosis takes place in RBCs as a result of which RBCs increase in size and burst, while the plant cell would remain about the same size because endosmosis is stopped due to the presence of rigid cell wall.
