Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

Scientists found molecular evidence supporting the idea that chloroplasts originated as energy-generating organelles and only ...

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 ...

The next step—ensuring chloroplasts can survive longer in animal cells. In the study, the researchers inserted energy-making chloroplasts from a rare red algae into Chinese hamster cells ...
