HOW LEAVES CHANGE COLORS!
We’d like to believe Mother Nature is responsible for all of the leaves changing colors in the fall because she spilled her paint but, truthfully, that isn’t how it happens. So why do leaves change to such an array of colors during the fall season?
For a simple explanation, we can compare leaves to a painter’s palette, (which makes sense to me because seeing a forest of trees in the fall often reminds me of a watercolor painting)! To continue, the leaves’ palette consists of three canisters of paint with unique names. The green paint is called chlorophyll. The yellow is called xanthophyll. The orange paint is called carotene.
In the summer, the green is used quite a bit!
The green canisters in the leaves fill with sunlight. The green color covers up all of the other colors in the leaves.
To help keep the leaves green, the chlorophyll (or green canisters in the leaves) continues to need water from the ground. The water is soaked up by each tree’s roots, travels up the trunk, and enters the leaves through tiny tubes in their stem.
As fall approaches, the weather gets colder, and the tree realizes winter is near and begins to prepare for the change in season.
A thin layer of cells grows over the water tubes in the leaves and closes them up, in preparation for the winter. No more water can get into the leaf!
Without the water, the green chlorophyll canisters start to disappear. Then the other color canisters in the leaf--the yellow xanthophyll and the orange carotene colors--are able to show through.
The leaves don't really "turn" a certain color; they just stop using their green canister of paint.
So far, You now have an explanation for the green, yellow and orange colors seen, but what about the purple, reds and browns also seen sometimes?
Remember when you learned about the cells building a wall to cover the tubes in the leaf's stem, so the water couldn't get in anymore?
The sap/sugar in the trees uses the same tubes. When the wall covers the tubes, sometimes sugar gets trapped inside the leaf. This sugar may cause the leaves to turn red or purple. When this happens, the leaves turn red or purple.
What makes the leaves brown?
When water stops flowing into the leaves and no food is being made inside them, they start to die. If you compare it to the palette example, the whole palette of paint dries up.
