Q:Mac Eye Pigments?
M.A.C pigments work really well. I have a few. And I haven't tried mixing medium solution.
Q:Where about in the beetroot is the pigment concentrated more?
I've known it to be in the skin and thats from a cooking point of view.
Q:Powdered paint/pigment question?
Wear protective gloves if you don't want your hands stained. You should also be concerned because many pigments have toxic chemicals that can absorb through the skin.
Q:What is the difference between primary and accessory pigments?
Photosynthesis in plants is dependent upon capturing light energy in the pigment chlorophyll, and in particular chlorophyll a. This chlorophyll resides mostly in the chloroplasts and gives leaves their green color. The range of light absorption in leaves is extended by some accessory pigments such as the carotenoids, but does not cover the entire visible range - that would make the leaves black! Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light. They also have a red pigment called phycoerythrin that absorbs green light and extends the range of photosynthesis. The red pigment lycopene is found in vegetables. Some red algae are in fact nearly black, so that increases their photosynthetic efficiency. Brown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range. These red and brown algae grow to depths around 270 meters where the light is less than 1% of surface light. Chlorophylla-a is the primary pigment for photosynthesis in plants. Its structure is shown at left. It has the composition C55H72O5N4Mg. It exhibits a grass-green visual color and absorption peaks at 430nm and 662nm. It occurs in all photosynthetic organisms except photosynthetic bacteria. Chlorophyll-b has the composition C55H70O6N4Mg, the difference from chlorophyll-a being the replacement of a methyl group with a CHO. It exhibits a blue-green visual color and absorption peaks at 453nm and 642nm. It occurs in all plants, green algae and some prokaryotes. There is usually about half as much chlorophyll-b as the -a variety in plants.
Q:How do scientists use a spectrophotometer to detemine the absortion spectrum of a pigment?
A pigment molecule absorbs at specific wavelength(s), meaning that when light of a specific wavelength is incident to the molecule only certain wavelengths are absorbed while others are transmitted. The spectrophotometer emits monochromatic light (light of only one wavelength) which passes through the pigment molecule and a detector determines the amount of light that is either absorbed or transmitted by the sample. This is done at wavelengths from the UV (180-330 nm) to the visible (330-700 nm) and the light that is either transmitted or absorbed is detected by the spectrophotometer and is able to be graphed with absorbance representing the y-axis and wavelength representing the x-axis. The resultant graph will depict the absorption spectrum of that particular pigment molecule. Hope that helps.
Q:7th grade biology/botany. Leaves + color Pigments + HELP!!!!! + Please!!!?
1shorter days and cooler temperatures 2they emerge from being obscured by the more numerous chlorophyll 3carotenoids,etc 4 senescense then abscission.the abscission zone has thin-walled cells,plant hormones decrease,a separation layer forms,cells form suberin thus isolating leaf from stem,fall
Q:What is a Pigment?
A pigment is essentially a substance that subtracts light to produce a variety of colors. In organisms, pigments are the colored matter (the substance in your cells that give your skin, tongue, hair, etc. their colors). In nonliving things such as painting, a pigment is the dry powder that is mixed with a fluid, creating a colored liquid which is then used to paint. As to how pigments work -- the pigment absorbs all light except the color you see. That color of light is reflected to your eyes. All kinds of substances can be pigments. I hope that was clear and answered your question!
Q:What is a pigment molecule?
pigments are molecules that absorb electromagnetic radiation. For example, the chlorophyll pigment in plants absorbs blue and red light, which is why they reflect green light (since green is the color not absorbed). Another example is melanin, which is the pigment that darkens the skin of people. Melanin absorbs UV to protect the skin. A pigment molecule struck by EM radiation in the visible region may absorb some of the light depending on what pigment it is.
Q:what are the different types of pigments other than chlorophyll?
Photosynthesis Pigments
Q:does photosythesis requier pigment moulecuels?
Photosynthesis requires Chlorophyll, which is composed of a mixture of pigments like chlorophyll a, chlorophyll b and xanthophyll. These pigments allow certain wavelengths of light to be used for photolysis, a required stage of the photosynthetic process.
