Science Monday #2: Why leaves are green

All about photosynthesis and other chemical processes

By  

Henry Reich's new MinuteEarth channel on YouTube, which gives animated explanations for Earth-based science topics, has published a two-part video (part 1 debuted last week) answering the question "Why Are Leaves Green?"

If it's been a while since your high school biology classes, take a gander at both videos to brush up on your photosynthesis.
