Q: Are carontenoids and anythocyanin accesory pigments.: This Site Might Help You. RE: What are accessory pigments? Are carontenoids and anythocyanin accesory pigments.

Q: explain an absorption spectrum of different pigments and the action spectrum ofphotosynthesis.: A pigment is any substance that absorbs light. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. Black pigments absorb all of the wavelengths that strike them. White pigments/lighter colors reflect all or almost all of the energy striking them. Pigments have their own characteristic absorption spectra. The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence. Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane (as in a chloroplast) www.emc.maricopa.edu/faculty/fara...

Q: Explain why plants need a variety of pigments to carry out photosynthesis?: It is particularly obvious in seaweeds. The pigment employed by the plant will vary according to the light available, so that seaweeds in shallow water tend to be green but those from deeper water are brown and then, where light levels are really low, seaweeds are red. In most of these cases photosynthesis is still carried out by chlorophyll but the associated pigments help with the absorption of the available light.

Q: I am trying to decide what kind of eyeshadow I should but I want something really pigmented and nice.: Best Pigmented Eyeshadow

Q: How are plant pigments like teammates on a sports team? And What is the goal of their teamwork??: Pigments in the reaction center work together to organize themselves in place, to protect the plant from injury from incidental light, and to absorb photons from the spectrum with each pigment catching its own portion of the incoming wavelengths. The accessory pigments catch and pass energy to chlorophyll a. Chlorophyll a is the specialist that plays the photon's electromagnetic energy into chemical. It splits water to release its electrons and hydrogen ions for use in the calvin cycle where glucose is manufactured. The goal is to fix energy into a usable organic form for the plant to live on.

Q: Can someone describe the role of accessory pigments in photosynthesis?: Accessory Pigments In Plants

Q: what roles do pigments have in energy transfer?: Pigments okorder /... When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. If the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the photosynthetic reaction center from the pigment array, to split water and take back an electron. Meanwhile the chlorophyll's electron passes to the electron transport chain to begin oxidative phophorylation.

Q: how to prepare coloured pigments?: Chemically, pigments fall into a number of large groups, but these are often arbitrarily divided into two major groups. The first group comprises pigments that contain nitrogen; it includes hemoglobins, chlorophylls, bile pigments, and dark-colored pigments called melanin, widespread in many animal groups and the chemical that is responsible for variations in the color of human skin. Related to melanins are the indigoids, of which the well known plant pigment indigo is an example. Riboflavin, which is also known as vitamin B12, is one of a number of pale yellow to green pigments that are produced by several plant groups. The second group is formed of pigments without nitrogen. Carotenoids are members of this group, as are the important plant pigments called flavonoids. In leaves, flavonoids selectively admit light wavelengths that are important to photosynthesis, while blocking out ultraviolet light, which is destructive to cell nuclei and proteins. Flavonoids are also important in flower color, in particular providing red and blue pigments. Bright fall colors are produced by the conversion of colorless flavonoids, called flavonols, into colored forms, called anthocyanins. Quinones provide many yellow, red, and orange pigments, including several useful dyes derived from insects that feed on plants containing the quinones. Cochineal, for example, is a red pigment obtained from the fat cells of scale insects that feed on cactus plants.

Q: pigment: its color (to our eyes) what color of light it absorbsChl a Chl bCartenoidsany right answers would bbe greatly appreicated thanks soo muchhh: pigment: .... reflected color to eyes .. what color of light it absorbs Chl a reflects green spectra between the blue and red absorption peaks. Some is absorbed at blue 450nm but most absorbed at red 680 - 700nm. Chl b reflects green spectra between the blue and red absorption peaks with a difference in which peak is stronger. Most is absorbed at blue 470 but also some at blue 430 and red 640 nm. Cartenoids reflect yellow, orange, or red and absorbs blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm. Xanthophylls are a common sub class of the carotenoid pigment group. Beta-carotene absorbs most strongly between 400-500 nm.
