Clearly explain the difference between osmosis, dialysis and diffusion and complete the following table by stating if the solution is hypo-, hyper- or isotonic.
Information: Osmotic pressure is the pressure that a solvent exerts against a semipermeable membrane, such as a cell membrane. The higher the solute concentration, the lower the osmotic pressure. Red blood cells have an osmotic pressure equal to that of a 0.90% (m/v) solution of sodium chloride and 5.0% (m/v) solution of dextrose. A solution that has a higher concentration that this is called hypertonic; one with a lower concentration is called hypotonic. Osmotic pressure is an important factor affecting cells. Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.Hypertonicity is the presence of a solution that causes cells to shrink.Hypotonicity is the presence of a solution that causes cells to swell.Isotonicity is the presence of a solution that produces no change in cell volume.When a biological cell is in a hypotonic environment, the cell interior accumulates water, water flows across the cell membrane into the cell, causing it to expand21.
