Carbon dioxide, as well as complex organic molecules (photosynthesis), are among the materials that make up a global carbon cycle that is made up of carbon-based components. Chlorophyll's job in a plant is to absorb lightusually sunlight. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Sugar molecules are stored in starch or sucrose by plants. From there on, the energy from the sun will ultimately become chemical energy that can be used by the organism for cellular processes. However, the overall reaction doesn't indicate the complexity of the chemical reactions or the molecules that are involved. This process begins with the absorption of light by specialized organic molecules, called pigments, that are found in the chloroplasts of plant cells. Chlorophylla-a is the primary pigment for photosynthesis in plants, but the range of light absorption is extended by chlorophyll-b, beta-carotene and other accessory pigments. The thylakoids are flattened sacs or vesicles. You may be wondering, why does chlorophyll absorb and reflect light? The xanthophylls comprise a diverse group of oxygenated carotenoids with varied structures and multiple functions ().In almost all photosynthetic eukaryotes, the majority of xanthophylls are bound with chlorophyll (Chl) molecules to proteins of integral membrane, light-harvesting complexes (LHCs) (2-5).The LHCs absorb and transfer excitation energy to the photosynthetic reaction centers to .
