Why is Chlorophyll green?

Chlorophyll is green because of the way it absorbs and reflects sunlight. The molecules of chlorophyll are structured in such a way that they absorb light most efficiently in the blue (430 - 450 nm) and red (640 - 680 nm) areas of the electromagnetic spectrum. Green light (500 - 550 nm) is not absorbed but reflected, making the chlorophyll appear green.
