Osmosis in potato cells Section 1: Planning Aim: To investigate how varying the concentration of sucrose solutions affects the rate of osmosis between the solution and potato cylinders immersed in it. Hypothesis: A substance, when dissolved in water, has a natural desire to dilute itself by bonding with surrounding water molecules. When a semi permeable membrane, such as a cell membrane separates two solutions, pure water flows from the weaker solution to dilute the stronger one until they are both the same strength. The term used to describe the flow of water through a semi permeable membrane separating two solutions of different concentrations is osmosis. In other words, osmosis is the process in which water passes in and out of plant cells thus controlling their turgidity. It is in fact the diffusion of water from places of high water concentration to places of low water...
