Taxonomy involves the naming and classification of living organisms by increasing specificity. The broadest category is the domain. There are three main domains, Bacteria, Archaea, and organisms have no nucleus and no membrane bound organelles. Bacteria have cell walls containing peptidoglycan and their ribosomal RNA is unique in the cytoplasm. The Eukaryota are single or multicellular organisms that have more complex cells which contain a nucleus. To name organisms, the worldwide binomial nomenclature naming system uses genus and species information.

The correct answer to complete the statement from your question is Bacteria.
Explanation: In taxonomy, Bacteria and Archaea fall under the category of prokaryotes, which are organisms that do not have a nucleus or membrane-bound organelles. Bacteria are characterized by having cell walls composed of peptidoglycan and unique ribosomal RNA. On the other hand, Eukarya comprises organisms whose cells are more complex, including those with a nucleus. The naming system used for these organisms is binomial nomenclature, which includes both genus and species.
