Verified step by step guidance1
Recall the three-domain system of classification, which divides all life into Bacteria, Archaea, and Eukarya.
Understand that prokaryotic organisms are characterized by the absence of a membrane-bound nucleus and other organelles.
Recognize that both Bacteria and Archaea are domains consisting of prokaryotic organisms, meaning their cells lack a true nucleus.
Note that Eukarya includes all eukaryotic organisms, which have cells with a nucleus and membrane-bound organelles, so it is not prokaryotic.
Therefore, the two domains that consist of prokaryotic organisms are Bacteria and Archaea.
