Investigating the Concentration of Cell Sap in Potato Tubes By Shakira Brooking This investigation is to find the concentration of cell sap in potato tubes, using the process of osmosis. Osmosis is the movement of water molecules across a semi-permeable membrane, from an area of high concentration, to an area of low concentration, through a concentration gradient. Apparatus: 6 beakers: The beakers were chosen rather than test tubes, merely because they are larger and give the potato tubes more space. Solution: Six different solutions were chosen (pure water, 0.2molar, 0.4molar, 0.6molar, 0.8molar, and 1molar), this meant that there would be a good range of results at the end of the investigation. 18 potato tubes: To make it easier on ourselves, it was decided that three potato tubes in each beaker would give a better and higher reading than just one. Scalpel: Used to cut the potato tubes into two. Scales: To measure potato tubes before...
