Photosynthetic pigments are pigments that reflect and absorb opposite ranges of visible light. The reflection of light gives the pigments their color. Photosynthetic pigments are comprise in autotrophs, which are organisms that use light push providedton to chance upon their own food in a process called photosynthesis. close to examples of autotrophs are plants, algae, and cyanobacteria [ (Speer) ]. There are many divers(prenominal) photosynthetic pigments in each of these that play a leave in photosynthesis, but the just about common pigments are chlorophyll a & b, phycocyanin, phycoerythrin and the carotenoids.
chlorophyll a is a kB pigment that is found in all plants, more or less algae, and in cyanobacteria (Speer). It is located indoors the cells chloroplast and embedded in the thylakoid membranes, where photosystem I and II are (Chlorophylls a and b). This pigment is the most common chlorophyll pigment, and also the most important pigment out of all the other photosynthetic pigments. It is the only pigment that is used in the very nerve centre of the photosystems. Through photosynthesis, chlorophyll a absorbs light energy, and turns it chemical energy to make glucose, which is sugar (Chlorophyll: Plants). Chlorophyll a absorbs mainly blue-violet light, slightly red-orange light and it reflects green light (Farabee).
The other common chlorophyll is chlorophyll b, and it is only found in green algae and plants (Speer). Like chlorophyll a, it is located inside a cells chloroplast and embedded in the thylakoid membranes, but it only resides in photosystem II (Billiet). Chlorophyll a and bs structure are alike, and also, both chlorophyll a and b are insoluble in water [ (College) ]. Chlorophyll b is an accessory pigment though, which means that it absorbs the light that chlorophyll does not and transfers it to chlorophyll a so it can be converted into chemical energy to make glucose (Nave). Chlorophyll b helps chlorophyll a by absorbing blue, orange, and a...If you want to demoralize a full essay, order it on our website: Ordercustompaper.com
