Archea and Bacteria are prokaryotes so they contain no nucleus or organelles, only a circular plasmid of DNA. They cannot form multicellular organisms. Archea are the more primitine of the two and can be found in extreme environments, such as hot springs and deep sea vents.

Eukaryotes have a nucleus with linera chromosomes that are much more complex. They are larger (about ten times larger) than prokaryotes, contain membrane-bound organelles and are able to form muticelled organisms.

Archaea are single-celled organisms that have unique cell membranes made of ether lipids. They can thrive in extreme environments such as hot springs, deep-sea hydrothermal vents, and salty environments. Archaea play important roles in nutrient recycling and some are involved in symbiotic relationships with other organisms.
