Bacterial cell structure - Wikipedia

The cell envelope is composed of the cell merane and the cell wall.As in other organisms, the bacterial cell wall provides structural integrity to the cell. In prokaryotes, the primary function of the cell wall is to protect the cell from internal turgor pressure caused by the much higher concentrations of proteins, and other molecules inside the cell compared to its external environment.
