Q:What pigments take part in photosynthesis?

Chlorophylla-a is the primary pigment for photosynthesis in plants, but the range of light absorption is extended by chlorophyll-b, beta-carotene (a carotenoid).

Q:What is the difference between dyes and pigments? Could you give some examples of each one please.

Dyes are dissolved in whatever solvent is used. Pigments are insoluble. Often a pigment is made by attaching a dye molecule to an insoluble particle. According to my sources a pigment is a coloring matter, usually in the form of an insoluble powder that is mixed with oil, water, etc. to make paint. The pigment lays on the surface and becomes part of the dry film. A dye is soluble in water and is used to color cloth, basket reed and other porous materials. A tube of white toothpaste would be a white pigment for some imaginary use. The same toothpaste, with a red dye added, would be a pink or red pigment. With an overwhelming concentration of dyes, or with black powder added, it could be a black pigment. Silver or metallic colorants can only be pigment.

Q:what are the differences between colorfast and non colorfast pigments?

I'm sure with enough research you will be able to find these answers and explanations in your text book. Or google them, maybe it will have pics to help describe if your more of a hands on learner. Good Luck.

Q:Hi what is pigment?i went on mac cosmetics and they sell all different kinds of stuff called pigment. I want to use it to make lip gloss but is it safe for my lips?please answer soon!

Pigment is colour. :]

Q:What is the difference between a pigmented eyeshadow and a non - pigmented one?

A pigmented eyeshadow means that it comes out on your eyes the color it is in the tray or palette for example you buy a black eyeshadow and when you swatch it or apply it to your eyes it looks dark gray or just completely different from how it appears to be

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:Can someone describe the role of accessory pigments in photosynthesis?

Accessory pigments help the plant absorb energy from different wavelengths of light other than those that are absorbed by the main pigment chlorophyl.

Q:thinking about the main role of pigments in photosynthesis...? explain how the pigments in colored objects suc?

photosynthetic pigment or antenna pigment is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. Green plants have five closely-related photosynthetic pigments (in order of increasing polarity): Carotene - an orange pigment Xanthophyll - a yellow pigment Chlorophyll a - a blue-green pigment Chlorophyll b - a yellow-green pigment Phaeophytin a[1] - a gray-brown pigment Phaeophytin b[1] - a yellow-brown pigment Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the spectrum. Chlorophyll a absorbs well at a wavelength of about 400-450 nm and at 650-700 nm; chlorophyll b at 450-500 nm and at 600-650 nm. Xanthophyll absorbs well at 400-530 nm. However, none of the pigments absorbs well in the green-yellow region, which is responsible for the abundant green we see in nature.

Q:Pleaseeeeee answer A.S.A.P Pleaseeee! Are pigments haram?

Most pigments for dyes and paints come from plants or minerals. What exactly do you need? The second part of your question about haram, needs some explanation, too.

Q:Why is it important for a plant to have more pigments than just chlorophyll?

If the plant only has chlorophyll, it is only able to absorb and use the wavelengths of light that correspond to chlorophyll, which is really limiting. Having other pigments allows it to use more wavelengths of light, which is more efficient.
