Detailed explanation-1: -The archaebacteria are a group of prokaryotes which seem as distinct from the true bacteria (eubacteria) as they are from eukaryotes.

Detailed explanation-2: -Archaea constitute the third domain of life (in addition to Eukaryota and Eubacteria), and they are single-cell bacteria-like organisms.

Detailed explanation-3: -Prokaryotes are microscopic organisms belonging to the domains Bacteria and Archaea, which are two out of the three major domains of life. (Eukarya, the third, contains all eukaryotes, including animals, plants, and fungi.) Bacteria and archaea are single-celled, while most eukaryotes are multicellular.

Detailed explanation-4: -Phylogenetically they are neither prokaryotes nor eukaryotes. They make up a new “primary kingdom, ” with a completely different status in the history and the natural order of life. We have named these organisms archaebacteria. The name reflects an untested conjecture about their evolutionary status.

Detailed explanation-5: -Explanation: A prokaryote is a cell which lacks membrane-bound nucleus, or any membrane-bound organelle. There are two domains of prokaryotes, Archaea and Bacteria. Archaea is prokaryotic because it doesn’t have a nucleus, nor any membrane-bound organelles.
