Bacteria cell diagram simple. The cytoplasm is enclosed by three layers the outermost slime or capsule the middle cell wall and inner cell membrane. Cell wall a solid layer surrounding the cell cell membrane a thin and structured bilayer of phospholipid and protein molecules that. It shows the cytoplasm nucleoid cell membrane cell wall mitochondria which bacteria lack plasmids flagella and cell capsule.
Text in this example. The cell wall of bacteria is located at the inner side of the capsule. They are also very versatile organisms surviving in extremely inhospitable conditions.
