10 evidence of endosymbiotic theory – Microbial Facts

The theory postulate that an aerobic bacteria established residency within the cytoplasm of a primitive eukaryotic cell. This bacterium would represent the precursor of the present mitochondrion. In similar fashion, the endosymbiotic uptake of an oxygenic phototrophic prokaryote would have made the primitive eukaryotic photosynthesis.
