Diffusion is the movement of particles from an area of high concentration to an area of low concentration. Diffusion is not to be confused with osmosis, which is the movement of water through a semi-permeable membrane.
Facilitated diffusion, also called carrier-mediated diffusion, is the movement of molecules across the cell membrane via special transport proteins that are embedded within the cellular membrane. Many large molecules, such as glucose, are insoluble in lipids and too large to fit through the membrane pores.assive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input.
