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: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
Detailed explanation-3: -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. [Prokaryote is derived from Greek, meaning “before nucleus"; eukaryote means “true nucleus."]
