Demonstration of osmosis - potato osmoscope osmosis is a special type of diffusion of liquids when two solutions of different concentrations are separated by a selectively permeable membrane, diffusion of water or solvent molecules takes place from the solution of lower concentration to the solution of higher concentration. Prediction osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution, through a semi permeable membrane the tiny pores in the membrane of the potatoes will allow the water molecules to go in and out of the potato cell, depending on the concentration gradient between the potato and the sucrose solution.
