If cells of onion peel and RBC are separately kept in hypotonic solution, what among the following will take place? Explain the reason for your answer.
(a) Both the cells will swell.
(b) RBC will burst easily while cells of onion peel will resist the bursting to some extent.
(c) a and b both are correct.
(d) RBC and onion peel cells will behave similarly.
Answer:
Option C is correct. When onion cell and red blood cells are placed in hypotonic solution, it will led to endosmosis (movement of water into cell) leading to the swelling of cell.
In the case of red blood cells, they burst easily compared to that of onion cell as red blood cells lack cell membrane which protects the cell from bursting.
