Adam Lewis 10Mr Biology practical In my experiment I am going to change the strength of the solution to see how this affects the rate of osmosis in potato cells. Task The variables that could affect the outcome Are : - Variety of potato, size of potato, surface are of potato, temperature, concentration of solution, volume of solution, time in solution. I am going to keep all the variables listed above the same, except for the concentration of the solution, which the potato will be left in. Previous Knowledge Osmosis is the passage of water from a weak to a strong solution through a semi-permeable membrane. Osmosis affects the turgidity and flaccidity of cells in the potato. A turgid cell is a cell that has the most water it could have in it. A flaccid cell is a cell that has little water in it. Prediction I predict that the potato in the 0% Solution will become larger than before...
