Detailed explanation-1: -The cell types in Bacteria and Archaea are considered as “prokaryotes.” The use of the term prokaryote was first introduced as a result of electron microscope studies showing a shared simple cell structure among bacteria (Stanier & Van Niel 1962).
Detailed explanation-2: -The bacteria are the oldest and simplest living organisms, and all of the bacteria are “prokaryotes, ‘’ meaning that they do not have a true membrane-bound nucleus as eukaryotes do.
Detailed explanation-3: -The two prokaryotic domains (Archaea and Bacteria) each comprise several smaller taxonomic groupings. Within the Archaea are the euryarchaeotes, crenarchaeotes, nanoarchaeotes, and korarchaeotes. Within the Bacteria are proteobacteria, chlamydias, spirochetes, cyanobacteria, and gram-positive bacteria.
