Plan On Osmosis Experiment Jonathan Anderson Introduction Knowing that osmosis (a diffusion of water) will occur across a semi-permeable membrane whenever there is a difference between the water concentration on the two sides of the membrane. And knowing that when this happens to all they will either become turgid if water flows into them, or plasmolysed if the water flows out of them, and therefore change their volume, we are going to test the hypothesis that: "If the concentration of a solution into which a cylinder of potato cylinders are placed is greater than a certain level the cylinder will contract, and if the concentration is less than that it will expand." Aim 1. To investigate the effect of increasing the concentration of sucrose solution on the rate of osmosis in potato cells. 2. To investigate the internal concentration of potato cells in terms of sucrose solution. Hypothesis For this investigation I think that the lower the concentration of...
