They are single-celled organisms that comprise cells with distinct properties that make them unique from the other two domains of life, namely Eukaryota and Bacteria. They can thrive in extreme environmental conditions, such as hot springs, salt lakes, etc. They use numerous sources of energy and display a diverse array of chemical reactions in metabolism.…

Archaea and Bacteria are two kinds of microorganisms that fall under the category of prokaryotes. Earlier, archaea were classified as bacteria, but now it is outdated as it has been found that they both have different biochemistry and different evolutionary history.   Archaea and Bacteria do not possess membrane-bound organelles or a nucleus.
