Explain Diffusion and Osmosis in cell structure?

Diffusion and Osmosis :  Diffusion through a cell membrane occurs as it does elsewhere, from an area of high concentration of solute to one of lower concentration.

Yet another mechanism, osmosis, moves water and dissolved substances across the cell membrane. Osmosis is really a type of diffusion in which water is the substance that moves from a high concentration to a lower one through a semi-permeable membrane.
