Umm.....they made oxygen for animals to breathe? Different pigments in chloroplasts attract different wavelengths of light and are involved in different steps in photosynthesis. Photosynthesis is a very complex reaction. If I recall correctly, if every single step to photosynthesis is written out, it would take up enough paper to fill a library =)

I think you should know that not every organsim has pigments in chloroplasts. At algae they are located in chromatophores and at cyanobacteria in inclusions of the cellular membrane
