Even though there are many millions of life forms on earth, all of them are made up of only two basic types of cell: All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). HeLa cells dividing under electron microscopy. Diffusion occurs when the concentration of a substance is higher on one side of the cell wall than the other, causing the substance to move to the side with a lower concentration.
