<P> The endosymbiotic relationship of mitochondria with their host cells was popularized by Lynn Margulis . The endosymbiotic hypothesis suggests that mitochondria descended from bacteria that somehow survived endocytosis by another cell , and became incorporated into the cytoplasm . The ability of these bacteria to conduct respiration in host cells that had relied on glycolysis and fermentation would have provided a considerable evolutionary advantage . This symbiotic relationship probably developed 1.7 to 2 billion years ago . </P>
