Verified step by step guidance

1. Understand the definition of prokaryotes: Prokaryotes are organisms that lack a nucleus and other membrane-bound organelles. They are typically unicellular.
2. Identify the domains of life: The three domains of life are Bacteria, Archaea, and Eukarya.
3. Recognize which domains contain prokaryotes: Both Bacteria and Archaea consist of prokaryotic organisms.
4. Differentiate between prokaryotic and eukaryotic domains: Eukarya is the domain that contains eukaryotic organisms, which have a nucleus and membrane-bound organelles.
