Question
What kind of organisms are present in domains Bacteria and Archaea?
- Unicellular and prokaryotic
- Multicellular and prokaryotic
- Unicellular and Eukaryotic
Solution
Understanding the Domains
The domains Bacteria and Archaea consist primarily of unicellular organisms that are prokaryotic. This means that these organisms do not have a nucleus or other membrane-bound organelles, which distinguishes them from eukaryotic organisms.
-
Bacteria: This domain includes a vast range of bacteria that can be found in almost every habitat on Earth, from soil to extreme environments. They can be beneficial, like those in our gut, or harmful, causing diseases.
-
Archaea: While also unicellular and prokaryotic, Archaea often thrive in extreme conditions, such as high temperatures or salinity. They have unique biochemical and genetic attributes that allow them to survive in these environments.
Final Answer
Both Bacteria and Archaea comprise unicellular and prokaryotic organisms.
