Biology Coursework Emmeline Hastings Aim: To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is. Prediction I predict that the potato segment in the distilled water will definitely gain in weight because the solution outside it has a much higher concentration of water then in the cell sap meaning Osmosis will occur and the potato segment take in water. I predict that 0.2M sugar solution will also gain weight because it still has quite a high concentration of water outside the potato. The potato in the 0.4M solution will gain weight but the potato in the 0.6M and 0.8M solutions will lose weight. The glucose concentration of the cell sap will be between 0.4M and 0.5M. Scientific Knowledge This experiment is based on the concept of Osmosis. Osmosis is the diffusion of water molecules from a region of high water concentration to...
