What is a cell that uses diffusion to move materials in and out?

I'm a little unsure of the question... Since most cells utilize diffusion and/or facilitated diffusion to bring in nutrients and oxygen, and to expel waste products.
One example may be enterocytes, which are the small intestinal cells responsible for bringing in glucose (sugar), amino acids, and electrolytes via diffusion and co-transport during the absorptive phase of food digestion. They also utilize diffusion, to subsequently transport those nutrients into the bloodstream, to then be processed by the liver, for the body's future use of them.
