- What evidence supports the endosymbiotic theory?arrow_forwardUnder the endosymbiotic theory for the origin of the eukaryotic cell. 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_forwardmake a drawing of a phylogenetic tree that contains all 3 domains of life. The tree should include at least three different animals, two plants, chemoheterotrophic bacteria, photoautotrophic bacteria, chemoheterotrophic archaea, thermophilic archaea and fungi.
