Chorophyll is a green substance that traps the sunlight.

You can do a simple experiment to see it (with adult supervision):
1. Put a leaf in a jar with some alcohol:
2. Wait for a while and see what happens:
3. Wait some more time (hours), remove the leaf and observe its colour:
Now we can see what colour the leaf would be without chlorophyll.
