Does endosymbiosis theory just refer to incorparation of mitochondria and chloroplasts?

Of course other cell organelles besides the mitochondria and chloroplasts may have originated through endosymbiosis. Unlike mitochondria, these organelles do not contain DNA, so there is less data to prove endosymbiosis. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
