Concept explainers
Interpretation:
The change occurs when red blood cells are placed in a hypotonic solution has to be identified.
Concept introduction:
Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution.
Hypotonic solution is the solution which has an osmotic pressure less than that in cells. A hypotonic solution causes cells to burst or to hemolysis.
Hypertonic solution is the solution which has an osmotic pressure higher than that in cells. A hypotonic solution causes cells to shrink or crenate.
Isotonic solution is the solution which has an osmotic pressure equal to that in cells. An isotonic solution has no effect on cell size.
