What would happen to a sample of your red blood cells if they were placed in a hypotonic solution?

Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm)

Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up.

The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC.

As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.
