Osmosis osmosis is the diffusion of water through a partially permeable membrane it is a special case of diffusion in that the concentrations of solutes in the water can effect how it occurs since water is a polar molecule, many substances dissolve in it these dissolved substances are termed solutes, and water is a solvent. - investigate the rate of osmosis in different vegetables (carrot, potato, swede, parsnip and sweet potato) in this coursework experiment i plan to find the rate of osmosis in different vegetables (carrot, potato, swede, parsnip and sweet potato.
