- Q: What is the difference between dyes and pigments? Could you give some examples of each one please.
- Dyes are dissolved in whatever solvent is used. Pigments are insoluble. Often a pigment is made by attaching a dye molecule to an insoluble particle. According to my sources a pigment is a coloring matter, usually in the form of an insoluble powder that is mixed with oil, water, etc. to make paint. The pigment lays on the surface and becomes part of the dry film. A dye is soluble in water and is used to color cloth, basket reed and other porous materials. A tube of white toothpaste would be a white pigment for some imaginary use. The same toothpaste, with a red dye added, would be a pink or red pigment. With an overwhelming concentration of dyes, or with black powder added, it could be a black pigment. Silver or metallic colorants can only be pigment.
- 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 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 love the colours that pigments come in but I don't know how to use them. Is there any easy way?
- You can go to a store that sells makeup and ask them how to use it. They will even show you.
- Q: What are iridescent magnetic effect pigments?
- Iridescent okorder /... (really long explanation)
- Q: how are the pigments in clothes differ from plant pigments?
- Pigments are pigments. They are made of molecules that absorb some colors and reflect others from the visible spectrum of light, which gives everything color. Black pigments absorb everything and reflect nothing, so black is the absence of color and it is why dark clothing are warmer in winter. White pigments reflect everything and absorb nothing, so clothing that is white is cooler in summer. Most plants have more chlorophyll, a green pigment, in them than other pigments, so the plant is overwhelmingly reflecting green back to our eyes and absorbing the red and blue ends of the spectrum. In fall, when the chlorophyll breaks down, we can see the yellow, orange, and red pigments that are also in the leaf for a few weeks. In this way, all pigments are alike. However, perhaps what your teacher is looking for is that the green pigment chlorophyll in plants not only absorbs red and blue wavelengths of light, it also uses that energy to excite electrons from the molecules of chlorophyll and send them through an electron transport chain that enables light energy to be converted to chemical energy and store it in the C-H bonds of glucose, which is made during photosynthesis. Other pigments, whether they be in clothes or other objects such as cars or just about anything else do not do this. Only plant chlorophyll, or the green pigment in plants, converts light energy to chemical energy. That is the one huge difference. Otherwise, like all other pigments, chlorophyll absorbs some wavelengths of light and reflects others, in the case of chlorophyll, green wavelengths of light.
- Q: I got this question from my A2 Biology but I can't find the answer. Does anybody know?
- Photosynthesis in plants is dependent upon capturing light energy in the pigment chlorophyll, and in particular chlorophyll a. This chlorophyll resides mostly in the chloroplasts and gives leaves their green color. The range of light absorption in leaves is extended by some accessory pigments such as the carotenoids, but does not cover the entire visible range - that would make the leaves black! Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light. They also have a red pigment called phycoerythrin that absorbs green light and extends the range of photosynthesis. The red pigment lycopene is found in vegetables. Some red algae are in fact nearly black, so that increases their photosynthetic efficiency. Brown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range. These red and brown algae grow to depths around 270 meters where the light is less than 1% of surface light. Chlorophylla-a is the primary pigment for photosynthesis in plants. Its structure is shown at left. It has the composition C55H72O5N4Mg. It exhibits a grass-green visual color and absorption peaks at 430nm and 662nm. It occurs in all photosynthetic organisms except photosynthetic bacteria. Chlorophyll-b has the composition C55H70O6N4Mg, the difference from chlorophyll-a being the replacement of a methyl group with a CHO. It exhibits a blue-green visual color and absorption peaks at 453nm and 642nm. It occurs in all plants, green algae and some prokaryotes. There is usually about half as much chlorophyll-b as the -a variety in plants.
- Q: How can you extract pure pigments from a sample of leaves in a form that you could test the absorbency of the various pigments??I don't know how to extract enough pigment in order to fill a cuvette and measure the absorbance, please help!! :D
- Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
- Q: I was intrested in buying some pigments on ebay but they dont say the name they just say these nubers #68 #69 #93 do u no what pigment name they are u could serch it that might help thank you
- there's okorder / i couldnt find the numbers you're better off going to the store and asking
- Q: Many of the microorganisms found on environmental surfaces are pigmented. Of what possible advantage is the pigment?
- So they can absorb different light frequencies to use for energy (from photosynthesis). Light travels in water according to the frequency (wavelength). So different pigmented organisms are able to exist in different environments, possibly reducing competition with other forms.
