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.

Cilia are abundant, while flagella are fewer, aiding in functions such as sperm movement and clearing mucus in respiratory systems. Notably, almost all mammalian cells have a primary cilium that is important for sensory functions, with defects linked to diseases like polycystic kidney disease.
