The energy that is created can be stored and is accessed later on by consumers. The consumers of the organisms break bonds while digesting the plant material and the stored energy is released into their perspective systems. The entire process of photosynthesis can be summarized as carbon dioxide and water reacting with light to create sugar, water and oxygen. Although put deceivingly simple terms, the process of photosynthesis’ energy conversion can be broken into two different reaction pathways, a light independent reaction and a light dependent reaction. In the light independent reaction, the energy stored by the plant as ATP and NADPH is used to fixate carbon dioxide and create sugar. Inversely, the light dependent reactions use the absorption of light to produce ATP and high energy electrons that are stored. The absorbing molecules found within the plant are referred to as pigments and each one absorbs different wavelengths. For example, chlorophyll absorbs red and blue light while other pigments absorb all other wavelengths of light that are left over. The “other” pigments found in plants fall into a group called carotenoids. Within the carotenoid group, the wavelengths for violet and blue light are absorbed. To understanding pigments in plants in relation to light, Thin Layer Chromatography (TLC) and spectroscopy are used to test the…
