In addition, prokaryotic cells generally lack membrane-bound organelles. Prokaryotic cells of the same species typically share a similar cell morphology and cellular arrangement. Most prokaryotic cells have a cell wall that helps the organism maintain cellular morphology and protects it against changes in osmotic pressure.

For example, some species of bacteria have a waxy lipid (mycolic acid) in their cell walls. These organisms generally do not Gram stain very well (those that do would usually appear gram positive) and are more clearly visible with the acid-fast staining technique.
