- Q: do all leaves extract contain the same pigments??why?
- Plants okorder /... Plants have classes of pigments that act as adjuncts to the chloroplast's chlorophyll, in several ways. Some are accessory pigments that broaden the range of absorbed light. These pigments are found in the light gathering arrays in chloroplasts. They also alter the color of the leaf depending on what specific pigments it has to gather light energy and that determines what is reflected (green is the basic reflected spectra but is might be yellowish or bluish green). The major accessory class of pigments, the carotenoids, collect light in the red to yellow wavelengths chlorophyll a can’t, then the carotenoids transfer the energy to chlorophyll a to process. Among the carotenoids are the xanthophylls that provide UV protection for the light gathering centers of the chloroplast. Plants adapt to situations and some just have fewer chloroplasts so have less chlorophyll and absorb less of the light. In low light situations they need fewer so variegated plants are possible. This reduced chlorophyll level allows small amounts of other pigments like the yellow pigment xanthophyll to show up.
- Q: list 5 mineral pigments and 5 animals pigments and how its produced
- Mineral Pigments: Lazurite (Lapis Lazuli), Vivianite (Blue Ochre), Riebeckite, Glauconite, Malachite, Jarosite, Limonite, Hematite, Goethite, Celadonite and Shungite Animal Pigments: Tyrian Purple, made from the mucus of a Murex snail Carmine, made from an insect in central and south America, called Cochinilla Natural indigo, made from plants of the genera Indigofera Rose madder, a pigment derived from the plant Rubia tinctorum Gamboge, I think is a dark type of mustard (seeds) Alizarin occurs in the root of the common madder (Rubia tinctorum) and in various parts of Indian madder (Rubia cordifolia). And regarding how they are produced, well each one has it?s own methods. You may want to search each of those names and you can find information for each one. Hope this helps, Bella
- Q: pretty self-explanatory...
- Pigments help in making food for the plants they also give color to it.Pigments are of different types which give different color to its leaves or fruits.Like mango is green first and then turns yellow coz green pigment is replaced by yellow pigment. Green pigment in most of the fruits is present only till it requires food and is raw.
- Q: I need to know the classes and sub classes of pigments classification
- organic pigment and inorganic pigment
- 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: As in like makeup pigments??????
- Makeup pigments are kind of like skin pigments. They are the diffent shades. For example; everyone has a different coverup or foundation pigment.(color)
- Q: a. chlorophyll ab. chlorophyll bc. chlorophyll cd. carotenoid pigments
- Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. 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. From this I would say the answer is c.
- 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: 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 )
- Q: If they are not the same, then what is the difference? Please help me out here.
- Yes, tannins are pigments but they aren't really the main plant pigment. Plant pigments usually refer to photosynthetic pigments (chlorophyll, carotenoids, etc.). These photosynthetic pigments give the leaves their green color (or yellow/orange in the fall). Tannins are non-photosynthetic phytochemical (involved in plant metabolism and internal functioning), but they are also a pigment. Tannins (and lignins) are brown. This is was gives dead leaves and wood their color. Tannins also leach out of the leaves when soaked in water (same process as brewing a cup of tea). So tannins are pigments when they leach out of leaves and stain water (or other things) brown, but they are not photosynthetic plant pigments. In other words, it depends on what context you are calling a tannin a pigment. In a live plant they are not a pigment (judgment call here). In a dead leaf or when they leach out of a leaf they are a pigment.
