Vedclass · Answer

(C) The osmotic pressure associated with the fluid inside the blood cell is equivalent to that of $0.9\% \ (	ext{mass/volume})$ sodium chloride solution,which is known as normal saline solution.If blood cells are placed in a solution containing more than $0.9\% \ (	ext{mass/volume})$ sodium chloride (a hypertonic solution),water flows out of the cells due to osmosis,causing them to shrink or collapse.If the salt concentration is less than $0.9\% \ (	ext{mass/volume})$ (a hypotonic solution),water flows into the cells,causing them to swell.The cell membrane does not dissolve in saline water.Therefore,assertion $(A)$ is correct,but reason $(R)$ is incorrect.

Assertion $(A)$: Blood cells collapse when suspended in saline water.
Reason $(R)$: Cell membrane dissolves in saline water.
