THE BIG PICTUREThese experiments led to work by laterscientists who finally discovered that in thepresence of light, plants transform CO2 and water

into carbohydrates and release oxygen.

There are two types of chlorophyll

Chlorophyll A & Chlorophyll B

Chlorophyll a absorbs thered & violetwavelengths best.

It absorbs very little blue light.

NEITHER KIND OF CHLOROPHYLL IS VERY GOOD AT ABSORBING green LIGHT!

That’s why plant have other pigments (like carotenoids). They help __ABSORB__ some wavelengths chlorophyll __DOESN’T_____; so the plant can USE MORE of the sun’s energy.
