Question

In brief state what happens when-1) a red blood cell is kept in concentrated saline solution 2) cells of onion peel are kept in hypotonic solution

Answer 1

1. RBC shrinks due to exosmosis
2. Onion peel swells due to endosmosis

Answer 2

$\sf\large\blue{\underbrace{{Answer}}}:$

If RBCs are held in a concentrated solution, it is said to be hypertonic since the water flows within the cell. This happens when the concentration of the solution is greater than the concentration of the inside of the cell, which allows RBC to shrink. So, the correct option is A, it will lose water and shrink
