To investigate the effect of surface area on osmosis in potato tissue Hypothesis: The larger the surface area of the potato, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. The potato pieces, which are left in the sucrose solution, will decrease in mass and the pieces of potato, which are left in water, will increase in mass. Theory: Osmosis: The diffusion of water through a partially permeable membrane, from a high concentration of water to a low concentration of water until the concentration is equal. As cell membranes are permeable they allow certain molecules to pass through them, such as water (H2O), through tiny holes in the membrane. These molecules contribute to the contents of the plasma around the...
