My aim was to investigate the effect of varying concentration of sucrose solution on the amount of osmotic activity between the solution and a piece of potato. Osmosis is defined as the movement of water or any other solution 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 particles through such as water 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. For this particular investigation I think that the lower the concentration of the sucrose solution in the test tube the larger the mass...
