Why Leaves Change Color in the Fall
from Ecogeeks : Untamed Science Video Podcast · host Rob Nelson
Why do leaves change color in the fall. Turns out, not many people really know the answer to this. You might think it is simply because the green color of the chlorophyll masks the other pigments. That's only part of the story though. Turns out, anthocyanins are produced in the plant in the fall. Learn more about the science of leaf change here.

What this episode covers
Every fall in the deciduous forests of the world, there is a miraculous change in the color of the leaves. The leaves turn from green into brilliant shades of yellow, orange, red, and purple. Sometimes you can see several shades on the same leaf. But why are these color changes happening, and what is going on in the plant? Fortunately, that’s the topic of this Untamed Science video. Rob and Canopy Biologist Meg Lowman, explain how it has everything to do with the pigments in the leaves. In fact, many of those pigments have been there all year and can only now be seen.
