- 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.
- Q: Please help me answer these Genetics problems. These are the problems that was assigned in the previous exams, but the professor doesn't provide the answer keys or a review session to go over these.Pigment in the mouse is produced only when the C allele is present. Individuals of the cc genotype have no color. if color is present, it may be determined by the A, a alleles. AA or Aa results in the agouti color, while aa results in the black color. In 3 crosses between agouti females whose genotypes are unknowns and males of the aacc genotype, the following phenotypic ratios were obtained. Female 1: 8 agouti 8 colorlessFemale 2: 4 agouti 5 black 10 colorless
- 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: I hear about it cause my Friend is albino and she was born with no pigments in her hair,skin or eyes
- Melanin is a pigment that is ubiquitous in nature, being found in most organisms (spiders are one of the few groups in which it has not been detected). In animals melanin pigments are derivatives of the amino acid tyrosine. The most common form of biological melanin is eumelanin, a brown-black polymer of dihydroxyindole carboxylic acids, and their reduced forms. All melanins are derivatives of polyacetylene. The most common melanin – dopamelanin – is a mixed copolymer of polyacetylene, polyaniline, and polypyrrole. Another common form of melanin is pheomelanin, a red-brown polymer of benzothiazine units largely responsible for red hair and freckles. The presence of melanin in the archaea and bacteria kingdoms is an issue of ongoing debate among researchers in the field. The increased production of melanin in human skin is called melanogenesis. Production of melanin is stimulated by DNA damage induced by UVB-radiation,[1] and it leads to a delayed development of a tan. This melanogenesis-based tan takes more time to develop, but it is long lasting.[2] The photochemical properties of melanin make it an excellent photoprotectant. It absorbs harmful UV-radiation and transforms the energy into harmless heat through a process called ultrafast internal conversion. This property enables melanin to dissipate more than 99.9% of the absorbed UV radiation as heat[3] (see photoprotection). This prevents the indirect DNA damage that is responsible for the formation of malignant melanoma and other skin cancers. Albinism (from Latin albus, white; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of an enzyme involved in the production of melanin.
- Q: PLEASE TRY!, to awnser ANY of the questions below.~What factors cause leaves to change colors. Where do these colors come from?~What are the names of the specific chemical pigments that cause the colors we see (reds, yellows, purples, browns, greens etc.) These are the same pigments (chemical that causes color) that give fruit their different colors.~What is the process (how it happens) that cause leaves to fall off of the branches. Explain at the cell level. (picture)Please try to awnser. Thanks.
- 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: 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.
- Q: wut is the diff between those 2?
- MAC pigment is a loose eyeshadow that comes in a jar. It is made with ingredients that help adhere to the skin it is also easy to blend and doesn't cake. It is also to use pigment if you want very intense colors. And MAC eyeshadow well it comes in a little case it is in powder form it's a lot easier to apply than the pigment because the pigment tends to get all over the place. Personally I like the eyeshadow better more shades and easier to apply.
- Q: I need to know the classes and sub classes of pigments classification
- organic pigment and inorganic pigment
- Q: What are the roles and type of plant pigments?
- Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change. Pigments are chemicals inside living things that absorb certain types of light. In plants, the pigment chlorophyll in leaves absorbs sunlight for photosynthesis to work, where the energy comes from. Chlorophyll absorbs all light except green, which is reflected. That's why most plants are green...
- Q: a. chlorophyll ab. chlorophyll bc. chlorophyll cd. carotenoid pigments
- 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: How can you extract pure pigments from a sample of leaves in a form that you could test the absorbency of the various pigments??I don't know how to extract enough pigment in order to fill a cuvette and measure the absorbance, please help!! :D
- Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
