Question

What are the 2 domains of prokaryotes?

Answer 1

Domains of Prokaryotes:

1. Prokaryotes are creatures without a nucleus or other organelles in their cells.
2. Early in the history of life, the two prokaryote domains namely Bacteria and Archaea, separated from one another.
3. Bacteria and Archaea are the prokaryote domains that are thought to have distinct evolutionary histories.
4. The majority of prokaryotes are tiny, single-celled creatures with a straightforward structure.

Bacteria:

1. Bacteria: Single-celled organisms that cannot be seen with the naked eye. Bacteria come in a wide variety, from pathogens that cause disease to helpful photosynthesizers and symbionts.
2. Small, single-celled creatures called bacteria exist. Nearly all areas of the world are home to bacteria, which are essential to their ecosystems.
3. Some organisms can survive in environments with high pressure and temperatures. In fact, it's thought that there are more bacterial cells in the human body than there are human cells.

Archaea:

1. Archaea: Microorganisms defining the limits of Earth being described and discovered under extreme conditions. Although archaea are varied and many of them exist in harsh settings, none of them are harmful.
2. Archaea are unique in that they can endure high temperatures or chemical aggression.
3. Extremophile archaea are those that can survive in hostile environments like hot springs and deep-sea vents.
