6.Mitochondria and chloroplasts are both thought to have become organelles within eukaryotic cells through endocytosis. Chloroplasts can be readily related to cyanobacteria while mitochondria are thought to have evolved from aerobic eubacteria. What present-day traits of these organelles provide evidence of these origins?
