... , who proposed that chloroplasts originated from cyanobacteria captured by a protozoan . Today both chloroplasts and mitochondria are believed to have such an origin; see endosymbiotic hypothesis . In Acquiring Genomes: A Theory of the Origins of Species , Lynn Margulis argued that symbiogenesis was t...

The resulting chemical energy is then captured in the form of ATP , and ultimately to convert carbon dioxide and water to carbohydrates and o...
