Where as hydrophilic substances (i.e., the substances which are soluble in water, e.g., glucose) do not PASS through a BIOLOGICAL MEMBRANE by simple diffusion. They are, therefore, TRANSPORTED across a cell membrane by facilitated diffusion (i.e., carrier mediated diffusion), which takes place with the help of certain transport proteins.
