Q: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:what is the function of pigment molecules in photosynthesis?
They absorb light from the sun
Q:What is pigment?
mac pigments are multi use. they're probably most popular as eyeshadows, but can also be used on lips, cheeks, nails, and pretty much anywhere. the mac pro store sells several mixing mediums, to change the consistancy of the powder, for the different uses, or they can be mixed with water/visine/etc.
Q:Physics: Compare and contrast pigment color with the color seen from a light.?
Pigments are chemicals that selectively absorb and reflect different spectra of light. When a surface is painted with a pigment, light hitting the surface is reflected, minus some wavelengths. This subtraction of wavelengths produces the appearance of different colors. Most paints are a blend of several chemical pigments, intended to produce a reflection of a given color. Mixing pigments is subtractive. Mixing light is additive. Let's take the primary pigments, red, blue and yellow. Red pigment is red because the chemical it is made of absorbs (subtracts) blue and yellow light that falls on it and reflects only red light to your eye. Similarly, blue pigment is blue because it absorbs red and yellow light and reflects only blue. So when you mix the three primary pigments together, you produce something that absorbs all of the light falling on it in equal amounts and reflects nothing to your eye. Thus, it appears black. In contrast, when you mix only red and blue light, there isn't any yellow in it, so the resulting light appears purple (the complement of yellow). Likewise, if you mix red and yellow light it appears orange (the complement of blue). If you mix all three colors of light together (in equal amounts), the resulting light appears white because it contains all of the colors of the spectrum. This explanation is sound, although greatly simplified. The two summaries above are not my own, nor do I claim them as mine.
Q:Explain light activation of pigments (absorption of light by pigments)?
A pigment is a substance that imparts color by absorbing some frequencies of visible light but not others. For instance, there are a lot of substances that absorb ultraviolet light into the visible spectrum, in other words they also absorb plain violet light. Since they absorb violet light but reflect back the rest of light, they appear yellow. Purple pigments, on the other hand, are quite rare because they absorb purple light (which has the highest energy of visible light) and reflect back everything else. When anything absorbs a photon of electromagnetic radiation (light, x-rays, ultraviolet, infrared, microwaves, gamma rays, radio waves), it is activated which means that it takes the energy of the photon and goes to an energy state that is higher by the same amount of energy that was in the photon. At the molecular level, energy is quantized, meaning its restricted to particular states. For instance, vibrational energy corresponds to infrared light: there are only certain ways, called modes, that a molecule can vibrate in, if it can't vibrate in an appropriate mode, it can't absorb the infrared radiation that corresponds to being promoted to that mode. That's why substances can be transparent. At the higher energy state, the substance might be able to participate in chemical reactions that it would not be able to participate in in a lower state. That's usually what is meant by light activation. So a pigment that absorbs visible or UV light might become activated and react with something or react in ways that it wouldn't be able to in the dark.
Q:Pigmented microorganism?
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:How do you use pigments?
technically, pigment is a coloured mineral of a few type it relatively is floor as fantastic as available. (i.e., cobalt is blue, iron produces reds, etc.) Pigment is a similar whether it fairly is in cosmetics, ceramics, or in paint. in spite of the undeniable fact that, cutting-ingredient chemical ingredients can even have the end results of coloring the ingredients of cosmetics, yet that would lead them to a colorant, no longer a pigment.
Q:Genetics Problem 5 - pigment in the mouse?
interior the 1st bypass AACC x aacc, discern a million will produce all AC gametes and discern 2 ac. Your F1 will all be AaCc. As all have the C allele they are going to be pigmented and as they're Aa they're going to all be agouti. Your F1 bypass is AaCc x AaCc. each and each discern can produce 4 gametes AC, Ac, aC, ac. To get all the genotypes you would be able to desire to entice a 4 x 4 Punnett sq.. each and each column and each and each row has between the 4 gametes in it and the cells comprise the blended genotypes. in case you count type up your genotypes you will discover 9 comprise the two A and C, those are agouti, 4 comprise cc, and all of those would be white regardless of the genotype at A, 3 comprise aa and C, those will all be black. So your phenotypic ratio would be 9:4:3 agouti: white: black the subsequent 3 crosses are all attempt crosses - you employ a recessive discern to artwork out the genotype of the different discern. a million. As lots of the offspring are colourless, you be attentive to that the two mothers and dads carry the c allele, as you pick cc for colourless mice. As there are no black mice, there is not any a allele interior the mum, as no aa offspring are produced. The bypass is AACc x aacc. woman gametes are AC or Ac and male gametes are all ac, offspring are the two AaCc or Aacc. 2. Is the opposite of bypass a million. There are black offspring so mom would desire to hold an a allele to furnish black mice, as there are no colourless ones, there is not any c allele interior the mum. you could write down the bypass and the F2 effect now. 3. This time all hues are produced, so the mum would desire to hold the two a and c alleles. Her genotype is AaCc, she would be able to offer 4 gametes as interior the 1st bypass and you will artwork out the resultant genotypes and phenotypes interior the F2.

Q:what is the right way to put on skin pigments?
Pigments are usually packaged in a finely milled loose powder form. After cleansing , toning and moisturizing,let the moisturizer absorb in the skin. Apply the skin pigments using a large compact powder brush/kabuki brush in a circular motion on face neck, then apply a second layer in a downward motion. Then use Evian water Mister to set the pigment. For eye pigments, put a thin layer of skin pigment first, then apply the eye pigment using a oval shaped dome brush
