- Q: What are MAC eyeshadow pigments? Are they just like regular eyeshadow.. are they used the same way? Has anyone tried them and liked them?
- NEVER TRIED THEM HEARD GOOD THANGS THO
- Q: what are the accessory pigments in plant photosynthesis?
- Accessory Pigments In Photosynthesis
- Q: i need pigment in powdered form and i need it to be oil based for my resin project. i was thinking about just crushing up artist oil pastels but i need it to be really fine with no chunks. sooo, i was wondering if anyone sells really fine oil based art pigment powders in a variety of colors. or do you know of i way i could crush up the pastels super fine so it will mix evenly into the resin? (i hope this made sence, i don't know much about art lol)thanks!!!:)
- Hi. okorder /... 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: What is the difference between a pigmented eyeshadow and a non - pigmented one?
- A believe a pigmented eye shadow will show up more vividly.
- Q: Know this ounds kinda obvious but just wanted to confirm, is there more pigment in the middle of the beetroot than on the edges?
- I've known it to be in the skin and thats from a cooking point of view.
- Q: I have been looking over the internet and have yet to find the details I need. Such as the function and development of Pigments.
- The most important characteristics of pigments are: 1. They impart a colour to the medium to which they are applied. Remember that you can get white pigments, titanium dioxide, and black pigments, carbon black is typical. The pigments impart a colour merely by their presence , they are mostly chemically inert.They need some binder to fix them to the substrate. 3.They are insoluble in the carrier in which they are processed. 4. Pigments can be inorganic or organic, but the majority have a metal in their structure. 5. Pigments can occur naturally, but synthetically produced pigments to precise standards are by far the most used in industry. 4. In contrast to this, colourants that dissolve in the medium in which they are processed are called dyes or dyestuffs. 5.Dyes are by and large purely organic in structure, and do not contain metals in their chemical formulation. 6. Dyes undergo a chemical reaction with the substrate which they colour. 7. There is also a third type of product called an extender or filler. In the surface coating industry clays, calcium carbonate, etc fill this role. They do not add any colour to the paint, they become transparent in the paint binder medium, because of their low refractive index. They add body to the paint.
- 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: how exactly do pigments work? i know that they absorb every color except the one that we see, but what are the exact physics or whatever behind the selective absorption of the light?
- Different pigments mostly absorb different range at different wavelength of light, but plant -as I know- mostly containing chlorophyll does not absorb green light so we see plants as green.
- Q: what are accessory pigments?
- Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjunction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant , while other algae may contain chlorophyll c or d. In addition, there are many non-chlorophyll accessory pigments, such as carotenoids or phycobiliproteins which also absorb light and transfer that light energy to photosystem chlorophyll. Some of these accessory pigments, particularly the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants. The different chlorophyll and non-chlorophyll pigments associated with the photosystems all have different absorption spectra, either because the spectra of the different chlorophyll pigments are modified by their local protein environment, or because the accessory pigments have intrinsic structural differences. The result is that, in vivo a composite absorption spectrum of all these pigments is broadened and flattened such that a wider range of visible and infrared radiation is absorbed by plants and algae. Most photosynthetic organisms do not absorb green light well, thus most remaining light under leaf canopies in forests or under water with abundant plankton is green, a spectral effect called the green window. Organisms such as some cyanobacteria and red algae contain accessory phycobiliproteins that absorb green light reaching these habitats.

- 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.
