Concentration of Cell Sap I am to come up with a method for estimating the concentration of solutes in cell sap, in particular, the solute concentration in potato cells. Cell sap is located in the vacuole, in the centre of plant cells, and makes up around 90% of the volume of the cell. The cell sap in the vacuole, when under pressure, keeps the cell rigid, by turgor pressure. Water moves in and out of the plant cells by osmosis, the diffusion of water across a semi-permeable membrane, in this case, the cell membrane, from an area of strong concentration, to an area of weak concentration. For example, if a solution with high glucose content were placed in visking tubing, a man-made semi-permeable membrane, which was subsequently placed in a solution with a low glucose concentration, osmosis would occur. Across the semi-permeable membrane, water molecules would move in both directions, but the...
