Little green powerhouses. (IMAGE) University of Tokyo Caption Chloroplasts give plants and algae their green hue, and enable them to convert sunlight into food and oxygen, via photosynthesis. The chloroplasts (right) in this study were taken from a type of tiny red algae (which are not actually always red, despite the name) called Cyanidioschyzon merolae (left). The alga came from the acidic hot springs of a volcano near Naples, Italy. Credit R. Aoki, Y. Inui, Y.
