Question

State True or False.

RBC on keeping in hypertonic solution shrinks down.

• A. True
• B. False

Answer 1

The correct option is A True

Option (A) is correct.
When red blood cells are placed in a hypertonic solution such as 4% sodium chloride solution (salt solution). water molecules diffuse out of the cell by osmosis. Water is rapidly lost. The red blood cells will shrink and probably die. This process is called crenation of red blood cells.
