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.
In the past, archaea were classified as bacteria and were called archaebacteria. But it was discovered that archaea have a distinct evolutionary history and biochemistry compared with bacteria. The similarities are that archaea and eubacteria are single-celled organisms that do not have a nucleus or organelles.n the past, archaea were classified as bacteria and were called archaebacteria.
