Q:Which of these is NOT a major photosynthetic pigment in plants?
Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. 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. From this I would say the answer is c.
Q:difference betwwen dyes and pigments?
Dye is used to change the color of things, like cloth. A pigment is like the color and texture of your skin. Or the color in paint.
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:Pls Help,<Mac Pigment> How to Apply?
Mixing okorder.com/watch?v=tbKmWd_Fl... I believe you can use vaseline for this as well. Also, it sometimes helps to use a sponge applicator, and yes, wetting your brush works as well. Start with a LITTLE. If you get a whole bunch on your brush you're going to make a huge mess.
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:What pigments take part in photosynthesis?
The green chlorophyll a & b
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:Bright Eye Shadow Pigment?
Coastal scents has amazing makeup palettes! They have an 88 color or 88 color shimmer win every color imaginable. They are very bright and pigmented. They blend well, look great, stay on all day and ont cost around $19. They are $18. And some cents. Very worth it. Check them out.
Q:What is pigment?????
It's like loose eye shadow.. except a more vibrant colour.. you'll get more colour pay off (usually). Pigments are nice - if you're just starting off.. go with Vanilla Pigment, it's uses are endless! And yes, you can use it on your lips.. sometimes I even use blush on my lips with a nice lip gloss.
Q:What are accesory pigments and why are they important?
Accessory pigments, also called, Photosynthetic Pigments or Chloroplast pigments, are pigments which are present within the cell of a Chloroplast used to harvest a greater spectrum of light.y are colored compounds which absorb and transfer light energy to chlorophyll. Pigments are light-absorbing molecules. In addition to chlorophyll,other pigments, principally yellow and orange carotenoids, as well asother forms of chlorophyll, are also present in green plants. These molecules absorb light and then pass the energy to the chlorophyll and accessory pigments, like the carotenoids, enable the plants to use more ofthe light than is trapped by chlorophyll alone.
Sinotio2, high technique enterprise with titanium series products production,scientific research and self distribution,the first and the only in china. It has titanium dioxide production line through chloride process which is the only line in mainland of China,and which has its self owned patents,The own line broke the technique blockade of the developed countries and promoted the development of Chinese titanium dioxide business.
