- Consider the two solutions separated by an ideal semipermeable membrane (permeable to water but impermeable to solute). Assuming complete dissociation of all the salts you can expect: a.) net water movement from side 1 to side 2 b.) net water movement from side 2 to side 1 c.) no net water movementWhat general conclusion can you make concerning the movement of water? There is always a net movement of water by osmosis toward (a) an isotonic solution, (b) a hypotonic solution, or (c) a hypertonic solution.What are some other biological examples of solutes affecting water potential and therefore movement of water in a living organism? Find examples in both plant and animal.
