Archaea and bacteria are two distinct domains of single-celled microorganisms, and they differ in several key ways. One primary difference lies in their cell membrane composition. Bacteria typically have cell membranes made of fatty acids, while archaea have cell membranes composed of ether-linked lipids, which gives them greater stability in extreme environments. Additionally, their cell walls differ; bacteria commonly have peptidoglycan in their cell walls, whereas archaea lack peptidoglycan and have unique cell wall structures. Moreover, their genetic makeup and biochemistry vary, with archaea often exhibiting metabolic pathways similar to those found in eukaryotic organisms. Despite their differences, both archaea and bacteria play critical roles in various ecosystems and biochemical processes on Earth.
