If iron, magnesium, or iron are deficient, plants may be unable to synthesize enough chlorophyll, appearing pale or chlorotic. When pigments are extracted, the antenna complexes, reaction centers, and ETCs have been disassembled, so the energy is given off as fluorescence and/or heat. Pigments like chlorophyll, through a complex process, pass photons from pigment to pigment until it reaches an area called the reaction center. Chlorophyll molecules are specifically arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts. The importance of pigment in photosynthesis is that it helps absorb the energy from light. It transports carbon dioxide and other nutrients to and from the chloroplast, as well as carrying away photosynthesis byproducts such as water vapor and oxygen. What is the overall purpose of the Calvin cycle? As a result of sunlight, it is possible to achieve this. What role do photosynthetic pigments play in the process of photosynthesis and where are these pigments found?
