That can be diffused.
Diffusion (a form of passive transport) across the phospholipid bilayer, which is semipermeable, is demonstrated through simple and facilitated diffusion. Simple diffusion does not require energy, while small, non-polar molecules move from a high to a low solute concentration. Facilitated diffusion also does not require energy, yet it needs a protein channel to move large and polar molecules.
