Difference between Archaea and Bacteria. Key Difference: Archaea are single-celled organisms that lack a nuclei and release methane as a product of metabolism. Bacteria are single-celled organisms that lack a nucleus, mitochondria, chloroplasts, golgibodies and ER.
Archaea, bacteria, and eukarya form three distinct branches of the Tree of Life or the phylogenetic tree, which traces the evolutionary history of organisms and indicates common ancestors. Archaea used to be thought of as bacteria, though this is an erroneous classification. Archaea and bacteria are definitely both tiny, single-cell organisms, which cannot be seen by the naked human eye called microbes.
