Understand the definition of prokaryotes: Prokaryotes are organisms that lack a nucleus and membrane-bound organelles. They are generally unicellular.
Identify the domains of life: There are three domains of life, which are Bacteria, Archaea, and Eukarya.
Determine which domains are prokaryotic: Both Bacteria and Archaea are classified as prokaryotes because they do not have a nucleus or membrane-bound organelles.
Recognize that Eukarya is not prokaryotic: Eukarya includes organisms with cells that have a nucleus and membrane-bound organelles, such as plants, animals, and fungi.
Conclude that the domains classified as prokaryotes are Bacteria and Archaea.
