Mitochondria increase in number within a cell by

  • A.growth and division of existing mitochondria
  • B.assembly from parts manufactured in the Golgi
  • C.budding directly from the outer nuclear envelope
  • D.fusion of vesicles from the endoplasmic reticulum

Answer: A

They divide in a manner reminiscent of bacterial fission, which is exactly what an endosymbiotic origin predicts. A cell that lost all of them could not rebuild them from its nuclear genes alone. Continuity of the organelle across generations is therefore unbroken.
