WebMay 21, 2024 · Archaea: Structure, Characteristics & Domain. Archaea is a relatively new classification of life initially proposed by Carl Woese, an American microbiologist, in 1977. He found that bacteria, which are prokaryotic cells without a nucleus, could be divided into two distinct groups based on their genetic material. WebThe cell wall allows the cell to withstand this osmotic pressure. In bacteria, the cell wall is made of peptidoglycan, a structure not found in either eukaryotes or archaea. This structure forms a meshlike sac around the cell and provides it with rigidity. Peptidoglycan is made up of polysaccharides linked by peptide bridges.
