Do eubacteria have cell walls?

Bacterial cell membranes are composed of fatty acids joined to glycerol by ester bonds (COOC), while archaeal membranes are composed of isoprenoids rather than glycerol, linked to fatty acids by ether bonds (COC). In addition, the archaea have a more complex ribonucleic acid (RNA) polymerase than bacteria. read more

The Eubacteria, also called just "bacteria," are one of the three main domains of life, along with the Archaea and the Eukarya. Eubacteria are prokaryotic, meaning their cells do not have defined, membrane-limited nuclei. read more

Eubacteria have a rigid cell wall made of peptidoglycan (rather than cellulose as found in plant cell walls). We can’t say that is because of “exactly” about this reason, it may be about evolution. read more

Most do, although there is a type of eubacteria that only has cell membrane and not walls. read more
