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 are interesting organisms in that they have genes that are similar to both bacteria and eukaryotes. Phylogenetically speaking, archaea and bacteria are thought to have developed separately from a common ancestor. Eukaryotes are believed to have branched off from archaeans millions of years later.
