Do prokaryotes have mitochondria?

No, prokaryotes do not have mitochondria. Mitochondria are membrane-bound organelles found in eukaryotic cells, which are more complex than prokaryotic cells. Prokaryotic cells, such as those found in bacteria and archaea, lack membrane-bound organelles like mitochondria. Instead, they have a simpler internal structure with no distinct nucleus or membrane-bound organelles like mitochondria, chloroplasts, or endoplasmic reticulum. Prokaryotes generate energy through various mechanisms, such as anaerobic respiration or fermentation, but they do not have mitochondria for aerobic respiration like eukaryotic cells do.
