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.
Although there are similarities between bacteria and human cells, there are many differences as well. Antibiotics work by affecting things that bacterial cells have but human cells donât. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall.
