Osmosis Aim What effects does the concentration of the sugar solution do to the mass of the potato? Scientific Knowledge Osmosis is the diffusion of water from a dilute sugar solution to a more concentrated solution through a selectively permeable membrane that allows the passage of water molecules but not solute molecules. Osmosis works because the water moves from higher concentrations to lower concentrations making the concentrations the same. Osmosis is a special example of diffusion where only water moves into or out of cells. Osmosis occurs because cell membranes are partially permeable. ... Osmosis will diffuse from a place where there is high concentration of water molecules such as a dilute sugar solution to where there is a low concentration of water molecules such as a concentrated sugar solution. ... I predict that the mass of the osmosis experiment will change. ... Another very important thing to make the experiment fair is to make sure all the potatoes are fully submerged in the solutions so the surface area being affected by osmosis on each potato is equal. ... I felt that this experiment of Osmosis was quit a fair test because we made sure that all our solutions were put in equally at the correct amount and did three set s of experiments with the solutions to make sure we did all the experiments correctly and accurately.
