Mary Ann (10) asks “Why are most leaves on trees green?”

Mary Ann. I sometimes think it is amazing that  leaves are so successful because they reflect green light ….the don’t want it.

Remember that white light from the Sun is a mixture of all different colours.Below you can see the result of white light being passed through a prism. the chlorophyll in leaf absorbs the deep blue and the red light and reflects the green light.

For red leaves the chlorophyll is hiding in the colour of the leaf. Our eyes cannot see it.
If you want to know a little bit more then ask another question.
