Our Hypothesis stated in the introduction of the paper was correct. The potato slices in the sucrose solution lost weight (grams), while the potato slices in the water gained weight (also in grams). Osmosis definitely occurred during this experiment. In one short hour changes can be seen between the weights of the potatoes. The skins on the potatoes are made of cellulose, membrane which does not allow osmosis to occur, or water to pass through under normal circumstances. In order for this process to be completed there are specialized pores in the cell wall called aquaporin’s. They are also for this specific to plant cells. The aquaporin’s allowed the water to be transferred from inside the potato (where the concentration of water molecules
