Endosymbiotic theory- the modern, or organelle- containing eukaryotic cell evolved in steps through the stable incorporation of chemoorganotrophic and phototrophic symbionts from the domain Bacteria. The hypothesis of endosymbiosis is at present the most widely accepted theory …

The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.
