If cells of onion peel and $RBC$ are separately kept in a 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.
$(c)$ Both $(a)$ and $(b)$ are correct.
$(d)$ $RBC$ and onion peel cells will behave similarly.

(C) Both $(a)$ and $(b)$ are correct. When the surrounding medium is hypotonic,water moves into the cells due to osmosis. This results in the swelling of the cells. $RBCs$ (Red Blood Cells) lack a cell wall,making them susceptible to bursting under osmotic pressure. In contrast,the presence of a rigid cell wall in onion peel cells provides structural support,preventing them from bursting.
