Final answer:
Both Archaea and Bacteria are domains made up of prokaryotic organisms without a nucleus. They reproduce asexually and have different cell wall compositions. Archaea often live in extreme environments while Bacteria are found in a wider range of conditions.
Step-by-step explanation:
True, both Archaea and Bacteria are domains consisting of prokaryotic organisms. These domains are entirely composed of unicellular organisms that lack both a nucleus and true membrane-bound organelles. They exhibit a number of similarities, such as the absence of a nucleus, asexual reproduction by division, and being encased by a cell wall, although the compositions of their cell walls differ. Archaea's cell walls do not contain the polysaccharide peptidoglycan that is found in bacterial cell walls. Additionally, Archaea are known to inhabit extreme environments, in contrast to Bacteria, which are found in more varied and less extreme conditions.
