Define the endosymbiotic theory. Explain how mitochondria and chloroplasts evolved by endosymbiosis. Explain 4 pieces of evidence for the Endosymbiotic Theory.
make 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. Identify both primary endosymbiosis events
on the tree and draw a line to connect it to the organism that would become the future organelle.
Discuss the Endosymbiotic Theory. Do you think it is a strong explanation on how the eukaryotes emerged on Earth?
