Biology Coursework 2003 An Investigation to find out how different strengths of salt solution affect potato cells through osmosis. Aim I aim to investigate the effect of different concentrations of salt solution on potato cells when osmosis occurs. Introduction I intent to set up this experiment using equally sized cylinders of potato submerged in salt solutions of different concentrations. I will then observe the percentage change in mass over a set period of time. This will show me how much osmosis has occurred. Scientific Theory of Osmosis Osmosis is defined as the solvent of any solution being able to pass through any semi-permeable membrane from a region of high concentration to a region of low concentration until both solutions reach a state of equilibrium. This means that water can flow through a porous material, such as a cell wall or visking tubing, in order to balance the levels of concentration. The molecules are...
