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 pigment?

Pigment is a substance that gives color to tissue. Pigments are responsible for the color of skin, eyes, and hair. I don't think you can buy pigment unless you're buying a product that changes the look of your pigment such as a self tanner lotion. Or a product may say the pigment is red but the product itself is not pigment. Pigment is a natural exsisting substance within your skin and inside your eyes and hair.

Q:i would like to now so i could put it in a marker thanks..

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:light absorption, which pigments are involved?

All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )

Q:I hear about it cause my Friend is albino and she was born with no pigments in her hair,skin or eyes

then she is natural coz she is not using any substances to colour or paint....

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

Accessory Pigments In Plants

Q:i need pigment in powdered form and i need it to be oil based for my resin project. i was thinking about just crushing up artist oil pastels but i need it to be really fine with no chunks. sooo, i was wondering if anyone sells really fine oil based art pigment powders in a variety of colors. or do you know of i way i could crush up the pastels super fine so it will mix evenly into the resin? (i hope this made sence, i don't know much about art lol)thanks!!!:)

Hi. okorder /... Those are all pure pigments, no hues or imitations. The prices may seem high, but even a half a pound of pigment is a huge amount. Prices I've seen on other sites are higher. I do not think it will work to crush up pastels, oil or otherwise, because they already have a binder and probably a lot of filler in them -- you will get a very weak color. Hope this helps.

Q:hahahai have no clue what that means!

n biology, a pigment or biochrome[citation needed] is any material resulting in color of plant or animal cells, which is the result of selective color absorption. Many biological structures, such as skin, eyes, fur and hair contain pigments (such as melanin) in specialized cells called chromatophores. Plant pigments include a variety of different kinds of molecules, including porphyrins, carotenoids, and anthocyanins. Chlorophyll is the primary pigment in plants; it is a porphyrin that absorbs red and blue wavelengths of light while reflecting green. Carotenoids are red, orange, or yellow tetraterpenoids. Anthocyanins (literally flower blue) are water-soluble flavonoid pigments that appear red to blue, according to pH. They occur in all tissues of higher plants, providing color in leaves, stems, roots, flowers, and fruits, though not always in sufficient quantities to be noticeable.Betalains are red or yellow pigments. Like anthocyanins they are water-soluble, but unlike anthocyanins they are indole-derived compounds synthesized from tyrosine. For more info visit : en.wikipedia.org/wiki/Biological_...

Q:pretty self-explanatory...

Pigments help in making food for the plants they also give color to it.Pigments are of different types which give different color to its leaves or fruits.Like mango is green first and then turns yellow coz green pigment is replaced by yellow pigment. Green pigment in most of the fruits is present only till it requires food and is raw.

Q:If you could explain it to me I would be very happy!

Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjuction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant antennae, while other algae may contain chlorophyll c or d. In addition, there are many non-chlorophyll accessory pigments, such as carotenoids or phycobiliproteins which also absorb light and transfer that light energy to photosystem chlorophylls. Some of these accessory pigments, particularly the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants.
