'''Chlorophyll''' is a pigment necessary for [[photosynthesis]].<ref>Wile, Dr. Jay L. ''Exploring Creation With Biology''. Apologia Educational Ministries, Inc. 1998</ref> It is still a mystery how exactly this molecule converts light ([[photon]]s) into useful chemical energy, but all the ingredients of the process are known. Once the chemical energy is created, it begins the well-understood [[Calvin cycle]] of photosynthesis.

When exposed to light, photosynthetic activity gives chlorophyll its characteristic bright green color; when light is not present the pigment has a much darker color.
