Which of the following is analogous to mesosomes of bacteria?

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

Answer: A

Correct answer: Mitochondria of eukaryotes

The mesosome is an infolding of the plasma membrane, long taken to be the site of the respiratory enzymes - hence the analogy with the mitochondrion. (Electron microscopy with better fixation suggests mesosomes are largely artefacts, but the comparison is the one the syllabus expects.)
