- Q: Why does a plant use several pigments instead of one or two?Why are plant leaves green?
- Pigments are a way for a plant to absorb the sun's energy in the form of light (photosynthesis). The different colored pigments absorb different wavelengths of light and pass it on directly to the plant to make energy, except for one class called the carotenoids, which much pass it on the the chlorophyll before anything happens The plants leaves are green because they absorb all the other wavelengthss (red, blue, oragne etc) except the green one, and the reflection of the green is what our eyes see.
- 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) The familiar colors of the rainbow in the spectrum include all those colors that can be produced by visible light of a single wavelength only, the pure spectral or monochromatic colors.
- Q: what is the relationship between chlorophyll a, accessory pigment?
- Chlorophyll is the pigment that allows plants—including algae—to convert sunlight into organic compounds in the process of photosynthesis. Chlorophyll a is the predominant type found in algae and cyanobacteria (blue-green algae), and its abundance is a good indicator of the amount of algae present in the waters of the Chesapeake Bay. Excessive quantities of chlorophyll a can indicate the presence of algae blooms. These usually consist of a single species of algae, typically a species undesirable for fish and other predators to consume. Unconsumed algae sink to the bottom and decay, using up the oxygen required by other plants and benthic organisms to survive. The presence of too many nutrients, such as nitrogen and phosphorus, can stimulate algal blooms and result in reduced water clarity. Chlorophyll a also plays a direct role in reducing the amount of light avalable to plants in shallow-water habitats. This directly impacts the ability of underwater bay grasses to thrive. Like their terretrial cousins, grasses need sunlight to grow. As chlorophyll a levels increase, the amount of sunlight reaching underwater grasses declines. Chlorophyll a is the main pigment, chlorophyll b and carotenoids are accessory pigments. accessory pigments help broaden the absorbtion spectrum, as chlorophyll a absorbs violet-blue and red light. with the addition of accessory pigments chlorophyll b and carotenoids, yellow-green (chlor b) and violet and blue-green light (caro)
- Q: Know this ounds kinda obvious but just wanted to confirm, is there more pigment in the middle of the beetroot than on the edges?
- I've known it to be in the skin and thats from a cooking point of view.
- Q: I am 33 years old and have pigment dispersion syndrome. My new doctor prescribed laser treatment, to prevent eye damage and potential sight loss. A previous doctor said to try drops, but only if my eye pressure became high-risk. Has anyone in Yahoo's network been in my situation and if so, what did you do?
- Rubbing eyes probably does not relate to pigmentary dispersion syndrome. While pigmantary dispersion syndrome can cause pigmentary glaucoma. Most glaucoma is not pigmantary glaucoma.
- Q: I'm onto black-berry.. I wonder what else is available in 98362.
- Pigments from the past came from rocks, minerals, plants, and other natural materials. Those things are all still available. You can take classes at some universities that teach how to make your own paints, or dry pigments. For native American pigments, you have to research which tribe used which colors. To be totally authentic you could visit the tribe of your choice and see if you can learn from them. Sticking to your own zip code will not net you much, usually.
- Q: Hi what is pigment?i went on mac cosmetics and they sell all different kinds of stuff called pigment. I want to use it to make lip gloss but is it safe for my lips?please answer soon!
- pigment is just color. the color shown or what makes a color. MAC is GREAT!!!!! its a color used to product a color or the actual color itself. either way....pigment means color.
- Q: In photosynthesis whats the difference between primary and accesory pigments?
- Primary pigments are molecules that convert light energy to chemical energy directly; chlorophyll is the primary pigment in all photosynthetic organisms. Accessory pigments are molecules that absorb photons which are not captured by chlorophyll. The presence of accessory pigments (found in the thylakoid membranes of plants) allows phototrophs (plants, algae, and cyanobacteria) to capture energy from the sun that would otherwise go to waste. The two most common types of accessory pigments are carotenoids and phycobilins. Some examples of carotenoids in common plants are: beta-carotein (carrot orange), lutein (marigold yellow), and lycopene (tomato red). Phycobilins are found only in red algae or cyanobacteria. The two most common phycobilins are: phycoerythrin (red), and phycocyanin (blue). The presence of accessory pigments in plants is masked by the presence of chlorophyll during the Spring and Summer seasons; that's why leaves are green most of the time. The color change from green to red, orange, or yellow that we observed during the Fall season is caused by the absence of chlorophyll; the accessory pigments are always present until the leaves fall as the trees go into dormant mode.
- Q: light absorption, which pigments are involved?
- All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )
