PLAN In this experiment I am intending to investigate the concentration of sugar in the cell sap of a potato-cell's vacuole. I will discover this using my knowledge of the biological process of Osmosis. Osmosis is the movement of solvent (usually water) through a semi-permeable membrane separating solutions of different concentrations. The solvent passes from a more concentrated solution to a less concentrated solution until the two concentrations are equal. Many cell membranes behave as semi-permeable membranes, and osmosis is a vital mechanism in the transport of fluids in all living organisms, the transport of water from the roots up the stems of plants is just one of these. APPARATUS For this experiment I will need the following apparatus: 1. One large potato, 2. Five glass beakers, 3. One measuring cylinder (50ml), 4. One potato corer, 5. One dissection tile, 6. One scalpel, 7. One measuring scale (2dp) 8. Ruler (1dp). To discover the concentration of sugar in the cell sap I...
