Archaebacteria-Organisms classified as archaebacteria have cell walls, contain fatty acids, have complex RNA polymerase and have systems of metabolism. These features distinguish archaebacteria from other organisms. Some traits, however, are shared with organisms in other kingdoms, including Eukaryotes and Bacteria.

Archaeans are prokaryotic, single-celled organisms. Their cells have a cell wall, but it is not made of the same substances found in the cell walls of plants, fungi, and bacteria. Despite lacking the organelles and nuclei seen in eukaryotic cells, the archaea are actually not that similar to bacteria.

Archaebacteria definition, a group of microorganisms, including the methanogens and certain halophiles and thermoacidophiles, that have RNA sequences, coenzymes, and a cell wall composition that are different from all other organisms: considered to be an ancient form of life that evolved separately from the bacteria and blue-green algae and sometimes classified as a kingdom.
