Quizplus · Accepted Answer

Mitochondria are thought to have descended from bacteria that were engulfed by a eukaryotic cell in a process called endosymbiosis. This is supported by the fact that mitochondria have their own DNA and reproduce independently within eukaryotic cells. The other organelles listed (nuclei, Golgi bodies, ER, and lysosomes) are not thought to have a bacterial origin.
