Q:mac pigments????????
MAC pigments actually have the name listed on the bottom. If the pigments on OKorder do not, you are more than likely looking at fakes.
Q:Which of these is NOT a major photosynthetic pigment in plants?
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:What is a pigment?????????!?
then she is natural coz she is not using any substances to colour or paint....
Q:How do you make paint pigments?
Pigments are specific minerals found in rocks. Then they are ground down and mixed with the binders for oil, acrylic, and watercolor paints. You can take art classes that teach you how to make your own paints. I have a cousin who hikes to find her own pigments and makes all the colors she paint with. If you'd like something less labor-intensive, you can buy the pigments you want from lots of art stores these days. They can be added to pre-existing colors to enhance them, or you can start from scratch to formulate your own colors. The bottles i've seen are around 8 ounces, and cost about $50. You will likely find books in the library and articles online that will help you learn to make your own pigments.
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:what is the right way to put on skin pigments?
Pigments are usually packaged in a finely milled loose powder form. After cleansing , toning and moisturizing,let the moisturizer absorb in the skin. Apply the skin pigments using a large compact powder brush/kabuki brush in a circular motion on face neck, then apply a second layer in a downward motion. Then use Evian water Mister to set the pigment. For eye pigments, put a thin layer of skin pigment first, then apply the eye pigment using a oval shaped dome brush
Q:Why do algae contain pigments other than just chlorophyll?
To use other wavelengths to perform photosynthesis.
Q:advantages of having accessory pigments?
Each photon has a particular wavelength, determined by the photon's energy. A pigment such as chlorophyll can only absorb photons in particular wavelength bands, matching the energies of available electron transitions to excited states. For chlorophyll, these bands are in blue and red -- the green color of most leaves is due to the waste light that is not absorbed by chlorophyll, while red and blue photons can be absorbed and used to power photosynthesis. An accessory pigment can absorb a photon that has a wavelength (color) outside of the bands that chlorophyll is able to absorb and can pass some of the absorbed energy on to chlorophyll, getting rid of the excess energy in another form, such as heat. A pigment might be tuned to absorb a photon of yellow light; the absorbed energy, stored in the excited state of an electron, is called an exciton (the photon becomes an exciton, so energy is not created or destroyed). The exciton can be passed to a chlorophyll, but only with the same energy as the red photon that the chlorophyll could normally absorb directly. The excess energy, the difference in energy between the yellow and red photon, must be dissipated in another form. This process allows a plant to harvest photons that would otherwise be unavailable to its photosystems. Consider how this would be an advantage to a plant living on a shaded forest floor, or to a planktonic cyanobacteria floating in the water below other photosynthetic algae, in regions where photosynthetically useful photons are scarce.
