(N/A)       Diffusion    Facilitated Diffusion        $1$. It is a passive process where substances move randomly from a region of higher concentration to a region of lower concentration.    $1$. It is a process where substances move across membranes with the help of special membrane proteins,even if they follow the concentration gradient.        $2$. It is a slow process and does not require any energy or specific transport proteins.    $2$. It is a faster process that is highly selective and requires specific membrane proteins (like porins or carrier proteins) to facilitate the movement of molecules.
