Q:I want to do some work with native american indigenous pigments.?
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:PLEASE HELP! I need an oil based pigment powder?
Hi. okorder.com/... Those are all pure pigments, no hues or imitations. The prices may seem high, but even a half a pound of pigment is a huge amount. Prices I've seen on other sites are higher. I do not think it will work to crush up pastels, oil or otherwise, because they already have a binder and probably a lot of filler in them -- you will get a very weak color. Hope this helps.
Q:Why is it important for a plant to have more pigments than just chlorophyll?
If the plant only has chlorophyll, it is only able to absorb and use the wavelengths of light that correspond to chlorophyll, which is really limiting. Having other pigments allows it to use more wavelengths of light, which is more efficient.
Q:Drosophila Eye Pigments?
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.
Q:Bright Eye Shadow Pigment?
Check out GOSH Cosmetics. They have tons of colours, many of which are bright. Try the waterproof eyeshadows and the effect powders.
Q:7th grade biology/botany. Leaves + color Pigments + HELP!!!!! + Please!!!?
1. Changes in pigment compsition is the primary reason for the changes in the colour observed during different developmental stages of leaves. 2. Each pigment has the property of absorbing light rays of certain wave lengths and reflecting rays of certain wave length. This is called chromatic property of the pigment. For example Chlorophyll absorbs all wavelengths and reflects green wave lengths. Hence it appears green in colour. Therefore the colour is in the light rays and not in the pigment. 3.Reds= Phycoerythrin; Yellows= Xanthophylls; Purples= Anthocyanins; Browns= different combinations of red and yellow pigments; greens= Chlorophylls; Blue= Phycocyanins. 4. Yes 5. The process of leaf fall is called Abcission. Leaf os an organ of definitive growth. It grows to its maximum size and becomes scenescent. Once scenescence sts in, all cellular materials that can be used elsewhere are translocated to other growing parts and the leaf becomes yellow. The water supply to the leaf is cut off. The phloem also becomes non-functional. At this stage a special layer called Abcission layer is formed at the base of leaf near the point of atachment to the stem. The abcission layer produces cork cells which plug the region. The layers of cells above the cork layer become deprived of water and food and die forming Separation layer. At this stage the leaf is attached to the base only by the xykem cells. By its shere weight the leaf breaks and falls. The most important point about abcission is that the exposed part of the leaf base is covered by cork layer which is impervious to entry of pathogens! Refer to any Plant Anatomy book for a diagram to show the longitudinal section of the abcission layer.
Q:what are three main families of pigments in plants?
Q:Physics: Compare and contrast pigment color with the color seen from a light.?
Pigments are chemicals that selectively absorb and reflect different spectra of light. When a surface is painted with a pigment, light hitting the surface is reflected, minus some wavelengths. This subtraction of wavelengths produces the appearance of different colors. Most paints are a blend of several chemical pigments, intended to produce a reflection of a given color. Mixing pigments is subtractive. Mixing light is additive. Let's take the primary pigments, red, blue and yellow. Red pigment is red because the chemical it is made of absorbs (subtracts) blue and yellow light that falls on it and reflects only red light to your eye. Similarly, blue pigment is blue because it absorbs red and yellow light and reflects only blue. So when you mix the three primary pigments together, you produce something that absorbs all of the light falling on it in equal amounts and reflects nothing to your eye. Thus, it appears black. In contrast, when you mix only red and blue light, there isn't any yellow in it, so the resulting light appears purple (the complement of yellow). Likewise, if you mix red and yellow light it appears orange (the complement of blue). If you mix all three colors of light together (in equal amounts), the resulting light appears white because it contains all of the colors of the spectrum. This explanation is sound, although greatly simplified. The two summaries above are not my own, nor do I claim them as mine.
Q:why do plants need more than one pigment for light absorption?
Pigments are molecules with an array of covalent bonds capable of absorbing a photon of light that has only a certain wavelength. The absorbed wavelength is only a fraction of the continuous range of wavelengths reaching the reaction center of a chloroplast. Each pigment species absorbs a different portion of the spectrum. So most photosynthesis works in combinations of pigments to absorb a across the visible spectrum and somewhat beyond. Some pigments (accessory photosynthesis carotenoid pigments) absorb useful wavelengths to pass the energy to chlorophyll A while the Xanthophyll Cycle pigments absorb potentially harmful high energy wavelengths for dissipation. Accessory pigments provide a range of spectra collection that allowed plants to adapt successfully to environments of differing light conditions. Pigments provide coloration to signal flower or fruit maturity to pollination partners or seed dispersal partners. Anthocyanins and carotenoids perform these communication functions. Phytochrome is a pigment that absorbs one wavelength only to toggle to another shape capable of absorbing at a different wavelength. Algae and plants both use this system to inform them of the time of year so they can synchronize with the best season in their habitat for reproduction efforts to succeed. Plants use phytochrome to regulate the photoperiod of flowering or seed germination.
Q:What do the pigments in leaves do?
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.
