- Q: i would like to now so i could put it in a marker thanks..
- Isn't all ink pigmented? A quick search for make your own ink turned up many recipes. Here is one: Basic Permanent Black Ink: 1 egg yolk 1 tsp gum arabic 1/2 cup honey 1/2 tsp lamp black (buy in a tube or make by holding a plate over a lit candle) Mix egg yolk, gum arabic and honey in a small bowl.
- 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 a pigment? Please describe it, and tell me the uses.?
- Pigments are a natural color in organisms. To understand pigments, you must understand the reflections of light. Pigments allows for organisms to have color, like the blue or brown in the eyes. For example, leaves in plants are color green because their pigments absorb all the colors because of photosynthesis except green and reflects off the color. Their plants are usually not green because they don't need to absorb light as much as the leaves does. Pigments depend on the type of light it absorbs. You are green in a dark room with green light right?
- Q: what are the differences between colorfast and non colorfast pigments?
- I'm sure with enough research you will be able to find these answers and explanations in your text book. Or google them, maybe it will have pics to help describe if your more of a hands on learner. Good Luck.
- Q: what the book says is that they 'harvest additional wavelengths.' i don't know what this means to how its an advantage.. can somone explain?
- Each photon has a particular wavelength, determined by the photon's energy. A pigment such as chlorophyll can only absorb photons in particular wavelength bands, matching the energies of available electron transitions to excited states. For chlorophyll, these bands are in blue and red -- the green color of most leaves is due to the waste light that is not absorbed by chlorophyll, while red and blue photons can be absorbed and used to power photosynthesis. An accessory pigment can absorb a photon that has a wavelength (color) outside of the bands that chlorophyll is able to absorb and can pass some of the absorbed energy on to chlorophyll, getting rid of the excess energy in another form, such as heat. A pigment might be tuned to absorb a photon of yellow light; the absorbed energy, stored in the excited state of an electron, is called an exciton (the photon becomes an exciton, so energy is not created or destroyed). The exciton can be passed to a chlorophyll, but only with the same energy as the red photon that the chlorophyll could normally absorb directly. The excess energy, the difference in energy between the yellow and red photon, must be dissipated in another form. This process allows a plant to harvest photons that would otherwise be unavailable to its photosystems. Consider how this would be an advantage to a plant living on a shaded forest floor, or to a planktonic cyanobacteria floating in the water below other photosynthetic algae, in regions where photosynthetically useful photons are scarce.
- Q: explain how the pigments in colored objects such as clothes differ from plant pigments
- Green pigments absorb light in the red and blue parts of the spectrum and reflect the green back to our eyes. The major functional difference between chlorophyll and say jade green is that only the chlorophyll in living systems can transfer the absorbed light energy and the excited electron to another molecule, thus trapping it. In biology, pigment is any material resulting in color in plant or animal cells which is the result of selective absorption. Some biological material has so-called structural color, which is the result of selective reflection or iridescence, usually done with multilayer structures. Unlike structural color, pigment color is the same for all viewing angles. Nearly all types of cells, such as skin, eyes, fur and hair contain pigment. Butterfly wings typically contain structural color, although many of them contain pigment as well. Creatures that have deficient pigmentation are called albinos. In the coloring of paint, ink, plastic, fabric and other material, a pigment is a dry colorant, usually an insoluble powder. There are both natural and synthetic pigments, both organic and inorganic ones. Pigments work by selectively absorbing some parts of the visible spectrum (see light) whilst reflecting others. A distinction is usually made between a pigment, which is insoluble, and a dye, which is either a liquid, or is soluble. There is no well-defined dividing line between pigments and dyes, however, and some coloring agents are used as both pigments and dyes. In some cases, a pigment will be made by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake.
- Q: We see pigments everywhere in products. They make a variety of things we see today. Where does it come from? Do they actually take a red rose pedal, grind the color and designate it as the color red?
- Color is made from a variety of methods.
- Q: I am planning on purchasing MAC, but what r the differences... thanks to all...I want to have an idea before I head to the mall.
- Pigments are really loose eye powders. For MAC, it's kind of like 'balls of sparkles' If you want really sparkly eyes, you'd probably want this. Dip your eye makeup brush in water, then in the pigment. I find this to work well, and it really compliments the product. It's best applied over a dark eyeshadow or primer. An eyeshadow is a packed together powder. (As you probably know) MAC eyeshadow comes on bright and radiant. So if you just want a simple look, this product works well. I suggest MAC - PaintPot. It's a creamy eyeshadow that is easy to blend. It's not waterproof, but it's difficult to rub off. It can act as a primer too.
- Q: HW HELP THIS IS COMLPCATED
- Pigments in plants color every part: red rose, orange carrot, purple plums. These pigments are not photosynthetic their function varies with location in the plant and the season. Chlorophylls are the primary photosynthetic pigment class found in chloroplasts. Flavonoids like the anthocyanins provide red, blue, purple, or magenta color to flowers and fruits. Color serves to attract pollinators and seed distributors. Recent literature reports some 550 different anthocyanins.
- Q: So i'm writing up a lab report and i'm just a little confused on why scarlet, rosy, cinnabar and vermillion mutants contain the same kinds and amounts of pigments found in wild-type according to paper chromatography. Since they're mutants shouldn't it be different? I don't understand how i'm going to explain that they are mutants when it appears that they have the same phenotype as wild-type. Thank you so much for your help!
- Man pigments determine the colour of the eye. If the composition of pigments is same in all the flies,how can the colour in which their eyes look differ?isn't this a contradiction?i suspect the accuracy of The chromatography test because even a very very slight change in the amount of pigment can significantly change the colour. The phenotype is always different in mutants due to different genotype. in genotype is taken for granted if a change in phenotype is present. Wait just got over into a nice point. Sometimes even if the pigment composition being same different colours m8 be produced due to different allotropes or iro of the same pigment might have different colours!though allotropes(not isomers) have same composition but differ in,their post translational changes r different.since post translational changes r indirectly influenced by genes.this completely explains this case.
