Wow! Really shows how mitochondria are actually just bacterial cells living inside us!

It's called symbiogenesis, for the record https://en.wikipedia.org/wiki/Symbiogenesis https://en.wikipedia.org/wiki/Symbiogenesis

  This might be a sign of different schools of thought on the matter, but I'd alwys seen it referred to as endosymbiosis (as your article also notes).

    Mitochondria are in endosymbiosis with eucaryotic cells. Symbiogenesis is the idea that eucaryotes came into being ("genesis") because some prior lifeforms joined in endosymbiosis.

      > the idea that eucaryotes came into being ("genesis") because some prior lifeforms joined in endosymbiosis is the theory of symbiogenesis Nope, endosymbiosis refers to the theory per se [1]. The 1966 article that "renewed interest in the long-dormant endosymbiont hypothesis of organelle origins" [2] referred to "the idea that the eukaryotic cell arose by a series of endosymbioses" [3]. The term symbiogenesis "was first introduced by the Russian Konstantin Sergeivich Mereschkovsky" in 1910. Hypothesis: the school split is an artefact of symbiogenesis (the original term) being revisited during the Cold War. (It also seems symbiogenesis refers to the broader biological phenomenon of symbiosis. There was a symbiogenesis of the Nemo-anemone relationship. Nemo is not endosymbiotic to anemones.)

  This photograph was of a bone cancer cell. I had heard that cancer (in general) suppressed mitochondria in preference for anaerobic respiration, and that apoptosis commonly involves these organelles. Not this cancer cell, it would seem.

    You're most likely talking about Warburg effect[1]. [1]: https://en.wikipedia.org/wiki/Warburg_effect_(oncology) https://en.wikipedia.org/wiki/Warburg_effect_(oncology)
