Question

Why are archaea in a different domain from bacteria?

Answer 1

Due to the certain differences in their morphology and habitats, the Archea are the separate domain of life in prokaryotes.

Explanation:

Archea is considered as the different domain of life in prokaryotes, as they are the most primitive type and known as the ancient microbes found in extreme niches such as hydrothermal vents, higher salt concentration, high temperature, and pressure etc. They also have morphological differences other than bacteria which are rarely to be seen in those harsh conditions on which archaea can thrive.
