Aim: to investigate the different effects of various concentrations of sucrose solution on potato cells. Introduction: Osmosis is a special type of diffusion. Osmosis happens when two solutions of different concentrations are separated by a selectively permeable membrane. A selectively permeable membrane has holes in it which are just big enough for water molecules to pass through, but not the much larger sugar molecules. Water moves across the membrane from a weak solution (high concentration of water molecules) to a stronger solution (lower concentration of water molecules). In this case, the two solutions are the cytoplasm inside the potato cells and the sucrose solution that I am placing my potato chip in. The partially permeable membrane is the cell membrane of the potato cells. When potato chips are placed in pure water, the concentration of water molecules surrounding the plant is higher than the concentration of water molecules inside the cytoplasm of...
