Verified step by step guidance

1. Understand the definition of prokaryotic organisms: Prokaryotes are unicellular organisms that lack a nucleus and membrane-bound organelles. They are characterized by having a simpler cell structure compared to eukaryotic cells.
2. Identify the domains of life: There are three domains of life, which are Bacteria, Archaea, and Eukarya. Each domain represents a major category of life forms.
3. Recognize which domains consist of prokaryotic organisms: Both Bacteria and Archaea are domains that consist of prokaryotic organisms. These domains include organisms that have a simple cell structure without a nucleus.
4. Differentiate between prokaryotic and eukaryotic domains: Eukarya is the domain that includes eukaryotic organisms, which have complex cells with a nucleus and membrane-bound organelles. This domain does not include prokaryotic organisms.
5. Conclude that the domains Bacteria and Archaea include prokaryotic organisms, while Eukarya does not.
