Difusion is the random motion of particles from a higher to lower concentration. Facilitated diffusion , unlike simple diffusion , needs specific protein channels for the particles to go through.

Diffusion is what one would call a form of passive transport.

Active transport needs ATP (adenosine triphosphate) to carry the particles around, and usually involves larger particles that cannot get carried through diffusion.
