Effect of solute concentration on osmosis in potato cells report introduction osmosis is the movement of water molecules from high concentration to low concentration through semipermeable membranes, caused by the difference in concentrations on the two sides of a membrane (rbowen, l) it occurs in both animals. If the concentration of salt is higher outside the cell, then water will move from the cell to the outside (osmosis) to equilibrate the concentration gradient that you have created water will leave the cell, and the cell will shrink (due to the decrease in volume.
