Osmosis Introduction: In this investigation, I plan to see which factors would affect the rate of osmosis in potato cells. Osmosis is the concentration gradient moving from a high concentration to a low concentration through a partially permeable membrane. I will weigh the potato chips before and after, if the weight increases, it shows that the potato chip has a lower concentration than the liquid it is in. Therefore, osmosis has taken place. Vocabulary (Taken From the Internet- Check Bibliography) Osmosis- the diffusion of fluids through a semi-permeable membrane or porous partition. Concentration Gradient- The change in solute concentration per unit distance in solute. Concentration gradients cause Fickian diffusion (spreading) of solutes from regions of highest to regions of lowest concentrations. In slow-moving groundwater, this is the dominant mixing process. Partially Permeable Membrane- A semi permeable membrane (or more accurately a selectively permeable membrane) is a membrane which will allow certain molecules or ions to pass...
