Final answer:
Prokaryotes are divided into two domains: Bacteria and Archaea, which also make up two of the six kingdoms in a six kingdom system. The domain Bacteria comprises all organisms in the kingdom Eubacteria, while the domain Archaea includes the rest of the prokaryotes. Prokaryotes are single-celled organisms without a nucleus, and they exhibit great diversity in form and function.
Step-by-step explanation:
Prokaryotes are divided into two different domains: Bacteria and Archaea. These two prokaryote groups also make up two of the six kingdoms in a six kingdom system.
The domain Bacteria comprises all organisms in the kingdom Eubacteria, while the domain Archaea includes the rest of the prokaryotes. Prokaryotes are single-celled organisms without a nucleus, and they exhibit great diversity in form and function. They are abundant and ubiquitous, inhabiting various environments ranging from extreme conditions like hot springs to more moderate environments like the human digestive system.
