Osmosis in Plant Cells Aim To find out how various concentrations of water affects osmosis in potato cells and to see if any patterns emerge that are related to osmosis. Background Information I shall begin this investigation with an explanation of what osmosis is. Osmosis is a special case of diffusion, which involves exchange of water particles across a semi-permeable membrane. Normally diffusion takes place in particles in the form of gas. Diffusion is where a high concentration of particles move over to where there is a low concentration of these particles until there is a state of equilibrium. This is when the particles have become evenly distributed within the volume in which diffusion took place. Osmosis is very similar to this principle, but will take place across a semi-permeable membrane. A semi-permeable membrane is a wall that has microscopic holes in it. Large particles (E.g. Sucrose, starch, protein etc.) are unable to...
