It is an important process occurring in all living organisms. Diffusion provides movement of substances in and out of the cells. The molecules move from an  area of high concentration  to an  area of low concentration until the concentration turn out to be equal throughout.                    Diffusion happens in  liquids  and  gases  because their particles move randomly from place to place.
