Aim: To investigate the effects of varying sugar concentration on the amount of osmotic activity between the solution and the potato tubes cut to a given size. Hypothesis: Osmosis is defined as the net movement of water molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement takes place across a partially permeable membrane e.g. a cell wall. This means that the cell wall will let 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, in our case (when both the potato cell and the solution have the same amount of sugar solution concentration,) Method: To make it a fair test certain aspects of the experiment had to been kept the same while...
