Kate's Biology Coursework. Investigating Osmosis. Aim I am going to investigate how different concentrations of water affect osmosis in slices of potato. Prediction I think that as the water concentration in a salt and water solution rises, then the weight of the potato will rise too. This is due to osmosis. I believe that because there will be a higher water concentration in the solution than in the potato then water will enter the potato to make the concentrations both inside and outside the potato equal. This corresponds with the scientific theory of osmosis: Osmosis: water moves from an area of high concentration to an area of low concentration across a semi-permeable membrane In this scenario the high concentration is the high water concentration in the solution of salt and water. The low concentration is in the potato slice. The semi-permeable membranes are the potato cell membranes. I used some preliminary experiments to help me along with...
