The ancestor of mitochondria and chloroplasts original became part of mutualism with a larger host cell. Which of the following best explains this mutualism? A) The mitochondria and chloroplasts provided specialized reproduction as part of the proto-germ line while the larger host cell provided energy for growth and reproduction. B) The mitochondria and chloroplasts provided gene products that could be used by the larger host cell for improved parasitization. C) The mitochondria and chloroplasts provided molecular energy in return for protection by the larger host cell. D) The mitochondria and chloroplasts produce toxins that the larger cell utilized to defend itself from other cells mutually increasing the defense of all those involved.arrow_forwardFigure 23.5 What evidence is there that mitochondria were incorporated into the ancestral eukaryotic cell before chloroplasts?arrow_forward
