facilitated diffusionfiltration
Molecules that permeate a plasma membrane by facilitated diffusion are typically larger, polar molecules that cannot pass through the lipid bilayer unassisted. These molecules rely on specific transport proteins embedded within the membrane to facilitate their movement across the membrane down their concentration gradient.
This process of transportation might be diffusion. Diffusion, by definition, is the process by which molecules spread out, or move from areas where there is a high concentration of molecules to an area where there is a low concentration of molecules.

osmosis is the movement of water across the plasma or cell membrane
In Facilitated diffusion materials are transported across the plasma membrane without using up any energy. Plasma membranes is made up of phospholipid bilayers consisting of proteins which help in the transportation of larger materials.

Diffusion, osmosis, facilitated transport and active transport- which requires energy to work.
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
