An experiment to show the progress of osmosis in potato tissues. Aim The aim of this coursework is to investigate the rate of osmosis in different concentrations of sugar solution using potato tissues. Prediction I think that in sugar solutions of high concentration, the mass of the potato will go down. This is due to the rules of Osmosis. Osmosis is the movement of water molecules across a partially permeable membrane, from a region of high water concentration to a region of low water concentration. There are two types of diffusion. These are: * Partially permeable membrane. This allows SOME particles to diffuse through things and not others. Most cell membranes are permeable to water. Diffusion of water through a partially permeable is 'The direction and rate of osmosis which depends on the differences in water concentration between the two sides of the membrane until equilibrium'. Only water molecules are small enough 2 diffuse through a partially permeable...
