MOVEMENT OF SUBSTANCES IN A LIVING POTATO TISSUE The aim of this experiment was to observe the movement of water molecules by the process of osmosis between living potato tissues and increasing amounts of glucose solution. The purpose of the above was to see if increasing the glucose concentration in the solution made a different to the movement of water molecules and also to use this to see if a weight change occurred in the potato pieces. METHOD All the equipment that was required for the experiment was collected; a large sized potato, potato bore, tile, tweezers and the different concentrations of glucose solutions, H O, 0.1 mole, 0.2 mole, 0.3 mole, 0.4 mole, 0.5 mole, all of which were labelled with the specific glucose content. Throughout the whole experiment safety was paramount and this experiment was conducted in a safe manner. The tile was placed on the work surface and the potato placed on top....
