Scientists Catch Photosynthesis in Action Researchers have snapped the very first images of photosynthesis as it happens. Photosynthesis is the process which plants use to convert light energy into chemical energy, which is then stored as sugar. Using the U.S. Department of Energy’s LCLS x-ray laser, the world’s most powerful, the researchers imaged the part […]
