Discuss the evolutionary order of appearance of the mitochondrion, chloroplast and ribosome, explaining your reasoning

By considering which organisms have each of the referred organelles, we can infer their evolutionary order of appearance.Ribosomes are present in every living cells, whereas mitochondria and chloroplasts are exclusive to eukaryotic cells. Moreover, while every eukaryotic cell, animal or plant, has mitochondria, chloroplasts can't be found on animal cells.Thus, the order by which these organelles evolved was: ribosome, mitochondria, chloroplast.
