Q:what are the three major photosythetic pigments?
three major pigments are 1.chlorophyll a 2.chlorophyll b 3.carotenoids chlorophyll a is the major pigment,chlorophyll b n carotenoid are the accessory pigments which help in absorption of the incident light of different wavelengths. another pigment xanthopyll-fucoxanthin is also present in some plants
Q:In photosynthesis whats the difference between primary and accesory pigments?
I think the primary pigment is/are the pigment(s) that lose the powered-up electrons. In plants this is typically chlorophyll a. The accessory pigments pass energy along to the photosystems, but (I think) do not themselves lose electrons.
Q:M.A.C pigments question!?
Buying okorder.com/... Good luck dear! If all else fails, I suggest going on specktra.net and asking on there. It's a MAC and make-up community forum and they're extremely helpful and informative when it comes to anything MAC!

Q:what is the relationship between chlorophyll a, accessory pigment?
Chlorophyll is the pigment that allows plants—including algae—to convert sunlight into organic compounds in the process of photosynthesis. Chlorophyll a is the predominant type found in algae and cyanobacteria (blue-green algae), and its abundance is a good indicator of the amount of algae present in the waters of the Chesapeake Bay. Excessive quantities of chlorophyll a can indicate the presence of algae blooms. These usually consist of a single species of algae, typically a species undesirable for fish and other predators to consume. Unconsumed algae sink to the bottom and decay, using up the oxygen required by other plants and benthic organisms to survive. The presence of too many nutrients, such as nitrogen and phosphorus, can stimulate algal blooms and result in reduced water clarity. Chlorophyll a also plays a direct role in reducing the amount of light avalable to plants in shallow-water habitats. This directly impacts the ability of underwater bay grasses to thrive. Like their terretrial cousins, grasses need sunlight to grow. As chlorophyll a levels increase, the amount of sunlight reaching underwater grasses declines. Chlorophyll a is the main pigment, chlorophyll b and carotenoids are accessory pigments. accessory pigments help broaden the absorbtion spectrum, as chlorophyll a absorbs violet-blue and red light. with the addition of accessory pigments chlorophyll b and carotenoids, yellow-green (chlor b) and violet and blue-green light (caro)
Q:What happens to the yellow pigments in a leaf during the summer months?
Carotenes and xanthophylls are always present in the leaves of plants. During the summer, the abundant chlorophyll masks the presence of the yellows, oranges, and reds that are also present. These other pigments are called accessory pigments and also absorb light energy used in photosynthesis.
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.
