  • Chloroplasts are also thought to be the descendants of endosymbiotic bacteria. Mitochondria and chloroplasts both have a genome separate from the main nuclear DNA, though most of their day-to-day functions have been shifted to the cell nucleus.

    Interestingly, some biologists advocate that the eukaryotic flagellum is also a descendant of an endosymbiont, specifically a spirochete, a kind of spiral-shaped bacterium. This has less traction, so far.
