Q:what are the three major photosythetic pigments?
A okorder.com/... gives the spectra (Action and Absorption)
Q:What is a pigment?
a pigment is a naturally produced substance in humans and nature in general, that reflects light that is perceived by our eyes as colour -a person without pigment would show totally white hair, and pale pink skin and eyes (the pink is from the blood vessels) -we have it to protect us from the sun --> naturally dark or tanned people have lots, rarely get burned or skin cancer; fair-skinned people were designed for the northern areas with less sunlight, burn easily
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.
Q:photosynthetic pigments?
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:how do you make pigmented ink?
Isn't all ink pigmented? A quick search for make your own ink turned up many recipes. Here is one: Basic Permanent Black Ink: 1 egg yolk 1 tsp gum arabic 1/2 cup honey 1/2 tsp lamp black (buy in a tube or make by holding a plate over a lit candle) Mix egg yolk, gum arabic and honey in a small bowl.
Q:what is the definition of color pigments?
Pigments are substances which are used familiarly to create pictures and printings. Pigments give an object a color when in a field of incident white light. Pigments themselves absorb a set of incident colors of light and reflect all others. When multiple pigments are mixed, their ability to absorb colors is added, such that their ability to reflect colors is subtracted.
Q:Bright Eye Shadow Pigment?
Kryolan and Mehron are amazingly bright and are used by youtube makeup guru AllThatGlitters21 ALL the colors are intense, but they have to be used wet. They have a very strong color payoff, and are so true to the palet color. Mac pigments are kind of on the expensive side, and they do give you ALOT of product, but sometimes alot is a bad thing because you cant always use all of it. Hope this helps :)
