Prokaryotic Domains: Bacteria and Archaea

What are the domains that prokaryotes are classified into?

Options:

1) Bacteria and Eukarya

2) Archaea and Monera

3) Bacteria and Protista

4) Bacteria and Archaea

Prokaryotes are classified into two domains: Bacteria and Archaea.

Final answer:

The correct answer is Bacteria and Archaea.

Prokaryotes are organisms that lack a nucleus or any other membrane-bound organelles. They are characterized by their simple cellular organization. These organisms are classified as belonging to two different domains in biological taxonomy, which are the Bacteria and Archaea.

Domain Bacteria includes the bacteria that are found nearly everywhere on Earth—soil, water, and even inside the human body. They come in different shapes, including rods, spirals, and spheres.

Domain Archaea includes organisms that are also bacteria, but they are different from the bacteria in domain Bacteria. They are known for thriving in extreme environments, such as hot springs, salt lakes, and the human gut.

Therefore, the correct answer is 4) Bacteria and Archaea.
