The Pigments of Photosynthesis Introduction In these experiments we examine various pigments used in photosynthesis. Photosynthesis is the metabolic process by which solar energy is converted to chemical energy and stored in plants. Animals and humans ingest these materials – breaking down the organic molecules to receive the stored energy. Therefore, directly or indirectly, photosynthesis is the source of nearly all energy used by living organisms. The pigments involved in this process absorb light energy and fall into three classes: chlorophylls, carotenoids, and phycobilins. Though they all solar energy, only chlorophyll can convert this energy directly into chemical energy. Experiment two examined the effects of evolution on pigment composition. Evolution results from natural selection – a natural process that’s primary goal is reproduction, those most successful in reproduction are naturally selected for predominant genes in the next generation that helped them reproduce and survive long enough to do so. The purpose of this experiment is

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
