A concentration difference between two areas is absolutely necessary for diffusion to occur. Without a difference in concentration, the particles would be evenly distributed and there would be no net movement of particles from one area to the other. A differentially permeable membrane can aid in the process of diffusion, but it is not absolutely necessary. A true solution refers to a homogeneous mixture of solute and solvent, but this is not a requirement for diffusion to occur. A non-permeable membrane would prevent diffusion from occurring. A living cell is not necessary for diffusion to occur, as diffusion can occur in non-living systems as well.
