The endosymbiotic theory proposed that the mitochondria and the chloroplast evolve from some types of bacteria which the eukaryotic cells engulfed.
The endosymbiotic theory tries to explain how the eukaryotic cells came into existence from prokaryotic cells. According to this theory, the eukaryotic organelles like the mitochondria and the chloroplasts were actually free living prokaryotes and were taken in one after the other via endosymbiosis.
This theory has been backed by evidences which establish the phylogenetic similarity between mitochondria and bacteria and also between chloroplast and cyanobacteria. The evidences include the presence of circular DNA in both chloroplast as well as the mitochondria and also the fact they divide by binary fission like bacteria.
