do bacteria have mitochondria?

Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do.

Bacteria are unicellular prokaryotic organisms found in different habitats. Prokaryotic organisms do not possess well-defined cell membranes, membrane-bound organelles, and well-defined nuclei with a nuclear membrane. They do not have mitochondria.

Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.
