WebbThe 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. Was mitochondria a virus? WebbUnderstanding: • The origin of eukaryotic cells can be explained by the endosymbiotic theory. An endosymbiont is a cell which lives inside another cell with mutual benefit. Eukaryotic cells are believed to have evolved from early prokaryotes that were engulfed by phagocytosis. The engulfed prokaryotic cell remained undigested as it ...
