What would happen to a sample of your red blood cells if they were placed in a hypotonic solution?
timofeeve [1]

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

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