Answer: The two prokaryotic kingdoms are Eubacteria and Archaea.
Explanation:
The kingdoms that contains organisms that are prokaryotes are Bacteria and Archaea. They are unicellular kingdoms and their members appear similar in shape and appearance. But, they are different from each other and that is why they are grouped into separate kingdoms. Bacteria are all known as prokaryotes, which are organisms that lack a cell nucleus and other membrane-bounds organelles, and tend to be less complex. Archaea does not have membrane-bound organelles either but they have a cell wall that does not contain peptidoglycan (which is found in Bacteria) and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
