Question

Name the phenomenon that result in the swelling of human red blood cells when they are placed in hypotonic salt/ sugar solutions

Answer 1

The phenomenon is known as osmosis.If a red blood cell is placed in water, water enters the cell by osmosis. Because the membrane is quite weak the cell will burst as the volume and therefore the pressure in the cell increases. Red blood cells shrink when placed in concentrated solutions of sugar as water moves out of them by osmosis.

Answer 2

Answer:A red blood cell will swell and undergo hemolysis (burst) when placed in a hypotonic solution. When placed in a hypertonic solution, a red blood cell will lose water and undergo crenation (shrivel).
