> Take away the mitochondria and bacteria… can cells live on their own?
We can live without bateria if we add with some food supplements.
mitochondria isn't considered alive, as a separate organism, AFAIK. It doesn't even have a species name. It's just a component of the host cell.
As I understand it, these new microorganisms are parasites. They're not essential for the functioning of the host cell like mitochondria are.

Citation needed. I would strongly doubt that this is true, because microbes also play a very important role in eg. immune defense. Remove all the mutualitic microbes from a human (eg skin, digestive tract) and the parasitic and pathogenic bacteria will take their place immediately.
