- Q: Is gel food coloring a pigment or a dye?
- Dyes contain pigments, my friend. What is a pigment? They are like little beads. Very very tiny beads of the same color. Then if you spread these out, they give the thing a color. For example, the little green beads in leaves give it a green color. Pigment in our hair gives it a blonde/auburn/brown/black color. What is a dye? A dye is a liquid made up of water and pigments. The pigments are dissolved in water (well not really dissolve just that you cant see the beads) so that it's easier for us to use it. Everything that has a color is made up of pigments. So, gel food coloring is a thicker version of a dye that contains pigments.
- Q: are photosynthetic pigments separated based on their polarity or based on their molecular structure?Thanks
- Molecular structure... Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought. Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which gives carrots their color. These compounds are composed of two small six-carbon rings connected by a chain of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments. One very visible accessory pigment is fucoxanthin the brown pigment which colors kelps and other brown algae as well as the diatoms.
- Q: How many pigments does grass reflect?
- Pigments are the colors that make grass look green. They are the pigments that do photosynthesis. Grass looks green because it reflects green light. It reflects the wavelengths of light that have the frequency of green light. Grass has other pigments that we do not see through the chlorophyll, but it is the light that is reflected.
- Q: Does albinism cause lack of ALL pigment, or just black pigment? Does this very on the species?
- Mammals and birds only have melanocytes (these produce varying amounts of brown or black pigment), so that's the only pigment that needs to be affected for them to display albinism. But other types of animals have multiple types of chromatophores. An albino snake, for example, would also need to have the cells that produce reds, yellows, and blues deactivated to appear white/colorless. For these animals to appear as albinos, all pigments would have to be affected.
- Q: ive been watching a lot of makeup videos on youtube and a lot of the girls use mac pigments. what exactly are they and how are they different from regular eyeshadow? are they easier or more difficult to use?
- Pigment okorder /....
- Q: I got this question from my A2 Biology but I can't find the answer. Does anybody know?
- Color. Chlorophyll a is light green. The accessory pigments, chlorophyll b is olive green, the xanthophylls are yellow/brown, and the carotenes are red.
- Q: Can someone describe the role of accessory pigments in photosynthesis?
- Accessory pigments help the plant absorb energy from different wavelengths of light other than those that are absorbed by the main pigment chlorophyl.
- Q: (After the fifteenth century)
- Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.
- Q: what is the function of pigment molecules in photosynthesis?
- Pigment Molecules
- Q: the absorption spectrum and the range of light reflected by each
- three major pigments are 1.chlorophyll a 2.chlorophyll b 3.carotenoids chlorophyll a is the major pigment,chlorophyll b n carotenoid are the accessory pigments which help in absorption of the incident light of different wavelengths. another pigment xanthopyll-fucoxanthin is also present in some plants
