An experiment to calculate the rate of osmosis in potatoes Skill Area P Planning Experimental Procedures Aim: To investigate the effect of varying concentration of sucrose in a solution on a potato cylinder of a given size Hypothesis: Osmosis is defined as the net movement of water molecules from a region of high water concentration, to a region of low water concentration, osmosis takes place across a partially permeable membrane, which only allows smaller molecules like water pass through it, and doesn't allow bigger molecules like sucrose to pass through. In this experiment the partially permeable membrane is the cell membrane of the potato cylinders. The water molecules will continue to diffuse until both sides of the partially permeable membrane have the same amount of water molecules and are equal- i.e. that there is the same amount of water molecules in the potato cylinder, than in the solution surrounding it. I predict...
