Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed ...

Due to their similarities to bacteria, mitochondria can actually trigger ... scientists could examine cells under the microscope, lyse them, and study the chemistry of cellular components, but ...

It appears that chloroplasts even siphon off some of the ATP generated by mitochondria, Mehta said. While the new findings do not definitively prove that this is how chloroplasts evolved ...
