Growing Up - Leaf Color

TRIVIA: Do leaves really change color in the fall? (mouse-over the leaf graphic)

Even our top scientists argued over this one! Whether you answered "yes" or "no" - you're right!

Yes, because if it looks different, it has changed its appearance.

No, because the color was there all along; it was just covered up by the green chlorophyll. So, actually, the green pigment is merely fading to reveal the color that was ALWAYS in the leaf.

The key to your answer is your interpretation of the word "change."
