Archaea

Key Questions

  • Answer:

    Explanation:

    Like the bacteria, archaea are prokaryotic cells. They do not have membrane bound organelles, nor do they have a nucleus.

    When archaea reproduce, they make a copy of their DNA and then the cell divides into two new cells. Each new cell gets a copy of the DNA molecule. This process is called binary fission .

  • Answer:

    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.

  • Answer:

    They constitute a domain of single-celled microorganisms.

    Explanation:

    The archaea are prokaryotes, so they have no cell nuclei or any other membrane bound organelles in their cells.

    The three kingdoms of archaea are Euryarchaeota, DPANN and Proteoarchaeota.
