Chloroplasts are also thought to have been engulfed and recruited to stay on as organelles[1], mind-boggling stuff. 1: https://en.wikipedia.org/wiki/Chloroplas

  This made perfect sense to Lyn Margulis, an evolutionary biologist who was once married to astronomer Carl Sagan. She put up with decades of skepticism and derision from older scientists before Woese and Doolittle identified the genetic data in chloroplasts that confirmed the theory.

    Already said in another comment, but I recommend the book "Sex, power, suicide" which explores the history of mitochondria and their evolutionary and todays role. The author also discusses Lyn's theories and partially absolves her (in particular on the symbiosis) but also highlights where her further theories don't hold up.
