Experiment to establish the effects of varying water potentials on potato tissue Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a piece of potato of a given size. Hypothesis: Osmosis is defined as 'the net movement of water or any other solution's molecules from a region in which they are highly concentrated to a region in which they are less concentrated.' This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through but does not allow bigger molecules to pass through. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other. For this particular...
