Bacteria have cell walls to assist them in avoiding problems with osmotic pressure. Gram positive bacteria have cell walls that are much thicker than those utilized by gram negative organisms. They also, like all other cells, have a cell membrane. The membrane contains many proteins that are specialized to allow transport of ions and solutes across the membrane and into or out of the cell. These channels do a great deal to maintain the integrity of the cell in the face of osmotic challenges.
