WebThe greater the difference in concentrations, the stronger the diffusion gradient and the faster the rate of diffusion. In osmosis, the net movement is always in one direction and the rate of osmosis depends on the molecular weight of the solutes, the surface area of the semi-permeable membrane, as well as the magnitude of the concentration ... WebThe primary differentiating factor between the two systems is the medium in which they are employed. Osmosis can only function in a liquid medium, but diffusion can occur in all three mediums (solid, liquid and gas). Furthermore, osmosis requires a semi-permeable membrane, while diffusion does not.
