"WebAll prokaryotic cells have a stiff cell wall, located underneath the capsule (if there is one). This structure maintains the cell’s shape, protects the cell interior, and prevents the cell from bursting when it takes up water. The cell wall of most bacteria contains peptidoglycan, a polymer of linked sugars and polypeptides. " - Is a major component of ribosomes
