MICROANATOMY

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 do not have a well-defined nucleus. It lacks cell organelles. It has single circular genetic material in which only one chromosome is present. Thus bacterial cell is considered as a prokaryotic cell.

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.
