- 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: why light and pigments are different?
- A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colourants, usually ground into a fine powder. This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
- Q: what the book says is that they 'harvest additional wavelengths.' i don't know what this means to how its an advantage.. can somone explain?
- 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.
- Q: What is pigment?
- Those are M.A.C. Pigments which are mineral powders that are very rich in color and shine. They can be used a myriad of ways and with so many different mediums. They can be used instead of eyeshadow or with it. It can go over creme based shadows. I have added M.A.C. pigments to body creme's, lip glosses, hair gels, nail polish (both clear and color). I've used them as highlighters for face and body. You can use them for virtually just about anything. They are one color when dry but tend to intensify when wet. It's a very versatile product. Lots of fun and tends to become a collectors item to many. For more on M.A.C. Pigments go to specktra / and register. It's basically a pro-M.A.C. site where you can even purchase samples of pigments.

- Q: What are leaf Pigments?
- Pigments that are present in the leaf that impart colour to the leaf are called leaf pigments. They are chemical compounds. Green colour in plants is due to Chlorophyll. Cholorophyll are also of different types Chlorophyll-A, Chlorophyll-B, Chlorophyll-C and Chlorophyll-D. Different colours are imparted to plants by different pigments. Some are Xanthophyll and Carotenoids.
- Q: Many of the microorganisms found on environmental surfaces are pigmented. Of what possible advantage is the pigment?
- So they can absorb different light frequencies to use for energy (from photosynthesis). Light travels in water according to the frequency (wavelength). So different pigmented organisms are able to exist in different environments, possibly reducing competition with other forms.
- 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.
- Q: How are plant pigments involved in photosynthesis?
- Plant pigments - as other pigments - interact with light to absorb only certain wavelengths. In plants the different sorts of pigments are useful to absorb available wavelengths of light and enable photosynthesis in shadow, in bright sunshine, in deep sea etc.: each pigment reacts with only a narrow range of the spectrum, there is usually a need to produce several kinds of pigments, each of a different color, to capture as much as possible of the sun's energy.
