Prokaryote

Definition

Prokaryotes are organisms whose cells lack a membrane-bound nucleus, mitochondria and other membrane-bound organelles; they include bacteria and archaea. All the intracellular water-soluble components (proteins, DNA and metabolites) are located together in the same volume enclosed by the cell membrane, rather than in separate cellular compartments.
