Q. A red blood cell (RBC) was kept in a certain solution for few minutes and it got burst. The said solution was
A) Isotonic
B) Concentrated sugar solution
C) Hypertonic
D) Hypotonic
Explanation
When an RBC is kept in hypotonic solution then, water enters the RBC by the process of osmosis (endosmosis). The RBC will increase in size and ultimately burst. Osmosis is the movement of solvent particles from hypotonic to hypertonic medium through semi-permeable membrane.
