Which eukaryotic organelle is regarded as analogous to the mesosomes of bacteria?

  • A.Golgi apparatus of eukaryotes
  • B.Lysosomes of eukaryotes
  • C.Mitochondria of eukaryotes
  • D.None of the above

Answer: C

Correct answer: Mitochondria of eukaryotes

The mesosome is an infolding of the bacterial plasma membrane, and it was long regarded as the site of respiratory enzymes - hence the analogy with the mitochondrion, which does that job in eukaryotes. (Modern work suggests mesosomes are largely artefacts of chemical fixation, but the comparison is the one textbooks and examinations use.)
