A: Facilitated diffusion differs from simple diffusion in that it crosses a membrane with the aid of passive transport proteins embedded in the membrane. Both types of diffusion are the movement of particles in solution from areas of higher concentration to areas of lower concentration.
Active Transport. Facilitated diffusion and active transport are two ways of moving materials across the cell membrane. These two types of transport have many similarities as well as differences. One similarity is in what is transported. In facilitated diffusion, ions, sugars, and salts are transported across the membrane. In active transport, ions, sugars, and salts are also transported.
