AIM: The aim of my experiment is to investigate the effect of sucrose solution on osmosis in potato cells, and what the point of equilibrium would be. I shall be observing how the mass of the potato chip changes in five different concentrations of glucose solutions. HYPOTHESIS: Osmosis is the diffusion of water molecules from a high water potential to a lower water potential through a partially permeable membrane. A partially permeable membrane, such as a cell wall, allows small molecules, such as water molecules, pass through it, but does not let bigger molecules such as sucrose through it. Cells placed in distilled water take up water by osmosis. This happens because the cell contains dissolved chemicals and therefore has a lower water potential than the distilled water surrounding it. As there are more water molecules outside the cell, more go in to the cell than out of it. The net movement...
