WebSep 26, 2015 · Facilitated diffusion is the movement of hydrophilic molecules or ions across the plasma membrane. The difference is, the diffusion is facilitated by transport proteins (i.e. carrier proteins or pore proteins) Remember, all three types of diffusion are forms of passive transport, and therefore don't require energy.
