Both mitochondria and chloroplasts are organelles. Mitochondria are used in cellular respiration and chloroplasts are used in photosynthesis. Photosynthesis and cellular respiration are opposite processes.Both are believed to have evolved from a living single celled bacteria that was engulfed by an early form of a plant or animal cell.itochondria are used in cellular respiration and chloroplasts are used in photosynthesis. Photosynthesis and cellular respiration are opposite processes.
Evidence that mitochondria and chloroplasts arose via an ancient endosymbiosis of a bacteria is as follows: 1  Both mitochondria and chloroplasts contain DNA, which is fairly different from that of the cell nucleus, and that is similar to that of bacteria (in being circular and in its size).he theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).
