You see, within every leaf are plant cells that contain within them special organelles that convert light into energy called chloroplasts. Within chloroplasts or different plant pigments

that absorb different wavelengths of light.

If you notice; well some of them are red, some of them are

yellow, some of them are brown. The leaves are changing this time of year. Today's episode is all about why that happens?

So. I'm here today at the Nature Research Center to learn about why leaves change color and to know maybe how that happens.

We're here; it can't be Meg. it's Meg Lowman; canopy Meg. My nickname is canopy Meg because I love leaves. I go around the world and climb into trees to look at leaves.

Meg began by giving me a very general overview of a typical leaf.

You see, within every leaf are plant cells that contain within them special organelles that convert light into energy called chloroplasts. Within chloroplasts or different plant pigments

that absorb different wavelengths of light.

Most of those are the green chlorophyll, but there are also other pigments like the orange or yellowish carotenoids.

Under the chlorophyll has always been these other colors of pigment. So, when that chlorophyll is sensitive to the cold and starts to die back we see those yellow colors. it's really really

beautiful. So that is the basic gist of color change and of course, that explanation works well.

You see the green right next to the yellow here and you might think what happened, but the yellow is always there and that is easy to understand.

But, we haven't talked about the Reds. Take this leaf for instance, notice how it's already turned yellow and if the fringes ,t's starting to turn red

The red generally comes from pigments called anthocyanins. The trick is that those pigments aren't in the leaves most of the year they're produced in the fall.

That's why you see those red pigments creeping in towards the middle of the leaf. But to really understand the

red let's get into the chemistry now.

Anthocyanins are produced when sugars combined with compounds called anthocyanins because anthocyanins needs

sugar for their creation.

Weather conditions that favor sugar production that's photosynthesis are essential and that means that bright sunny fall days produce the best colors

I hope that helped to understand why leaves change color in the fall and has everything do its chemistry right but remember that not all leaves change color.

In fact if you're like me and you have these giant oak trees in your backyard then you'll know that all they do is they turn brown.

These leaves, you have to wake up at the end of the year and it's really not fun.

This has to do with another compound it's called tannins in tannins are what turns your tea brown and it's also part of

the reason why oak leaves are really not all that good to eat.

Plant leaves obtain different colours due to the presence of different types of pigment like carotinoids (yellow, orange), anthocyanin (purple) etc. But chlorophyll is also present on these leaves but remains hidden or musked among other pigments. These chlorophylls perform photosynthesis just like other green plants. So coloured plant leaves also carry out photosynthesis like green plants.
