Why Do Leaves Change Their Color?

Why Do Leaves Change Their Color?

        Many people do not think about why leaves change color, they just think about as something that leaves do when the temperature starts going down. But there is a reason. OMG there is???!!!
Woahhhh they're changing cooool
Yeah there is! =D Now lets talk 'bout dat reason. So basically, the chlorophyll in the leaves reflect green light, which makes the leaves green. When the sun starts setting earlier and earlier, the chlorophyll, that green pigment in the chloroplasts, the plant starts to stop producing chlorophyll. When it does that, it reveals the other colors like yellow, orange, and brown, which were ALWAYS THERE. YEAH THAT'S RIGHT I JUST BLEW UR MIND BRO. So, after that then the leaves fall and then they regrow in the winter. But it ain't dat simple.

First of all, lets talk about why the leaves change their color. See, there are two pigments that cause the leaves to be colored. The pigments that make leaves yellow, orange, or brown are called carotenoids, and the pigments that make leaves red or purple are anthocyanins. Some examples of foods that have carotenoids are pumpkins and carrots (carrot = carotenoids). Examples of foods that have anthocyanins are blueberries and strawberries.

Now for why leaves fall off the tree. See, there's a little piece of cork that grows in the base of the leaf between the leaf and the branch. Every fall, the cork grows to its limit and completely blocks off the leaf from the rest of the tree. The leaf then is blown off by the wind or simply gets so feeble it falls.

A factor of how dull or bright a leaf is in the fall depends on how the weather is. Warm weather makes the colors brighter, while cold and dry weather makes the colors more dull.

Some trees do not lose their leaves in the winter. This is because the trees have an anti-frost on the leaves, so they are protected from the cold. They also do not require as much sunlight to make food.

Well, that's all for today. Scientific Waffle out.
