Diffusion is the net movement of molecules or atoms from a region of high concentration with high chemical potential to a region of low concentration with low chemical potential.
Simple diffusion allows non-polar molecules to pass through and a little amount of H20. On the other hand, Facilitated diffusion allows ions and polar molecules across the mem â¦ brane because it contains carrier proteins. It is highly specific to substances it diffuses across the membrane.acilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.
