- Q: thank you very much for your help!
- it gives nutrients to the plantsfood to all the parts of the plants.
- Q: like what's the definition relating to sunlight
- Pigments are substances which are used familiarly to create pictures and printings. Pigments give an object a color when in a field of incident white light. Pigments themselves absorb a set of incident colors of light and reflect all others. When multiple pigments are mixed, their ability to absorb colors is added, such that their ability to reflect colors is subtracted.
- Q: What do chlorophylls, cartenoids and phycobilins reflect? And what wavelengths of light do they absorb?
- Carotenoids generally reflect yellow, orange, or red and absorb blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm Beta-carotene absorbs most strongly between 400-500 nm. Fucoxanthin absorbs light primarily in the blue-green to yellow-green that penetrates deeper in water, peaking at around 510-525 nm and again at 450-540 nm. This reflects a yellow brown giving brown algae their color. Phycobilins are not found in leaves except as a phytochrome. They occur in Cyanobacteria (bluegreen algae) and Rhodophyta's (red algae) photosynthetic pathways as accessory pigments a part of the light reaction pigment systems energy donors to the reaction center. Phytochromes respond to far red between 700-800 nm. Phycoerythrin is a phycobilin pigment in rad algae that reflects red light and is therefore responsible for the color of most red algae.
- Q: How do you use pigments?
- You can use Pigments for multiple things, eyes, cheeks and lips. -Eyes: With your clean fingers or with a small eyeshadow brush apply the pigment gently to your lids. If its a light color like white, apply it on the inner corner and under the brows. If its darker, like dark brown, apply it on the crease. You can also use it to line your eyes, I like to mix pigments with some moisturizer and with a really thin brush line my eyes. If its a matte pigment (with no shimmer or glitter) you can use it to fill in your brows. Lastly, you can use it on your lashes! I use some hair gel or clear mascara and I mix it with some pigments, I apply it with my finger or with an old mascara wand :) -Cheeks: Use it as a blush if its a pink, red, orange or coral color. Apply a small amount with a blush brush onto the apples of your cheeks. If its a white, very light brown or pink, use it as a highlighter. Apply with a small brush under you undereye area. If its a darker brown, use it as a bronzer or conturing powder. -Lips: Mix pigments with vaseline, olive oil or clear lipbalm to get a tinted gloss. If you want more precision, use a small brush to apply it. As you can see, Its all about the brush you use!! Hope it helped :)
- Q: what the book says is that they 'harvest additional wavelengths.' i don't know what this means to how its an advantage.. can somone explain?
- Each photon has a particular wavelength, determined by the photon's energy. A pigment such as chlorophyll can only absorb photons in particular wavelength bands, matching the energies of available electron transitions to excited states. For chlorophyll, these bands are in blue and red -- the green color of most leaves is due to the waste light that is not absorbed by chlorophyll, while red and blue photons can be absorbed and used to power photosynthesis. An accessory pigment can absorb a photon that has a wavelength (color) outside of the bands that chlorophyll is able to absorb and can pass some of the absorbed energy on to chlorophyll, getting rid of the excess energy in another form, such as heat. A pigment might be tuned to absorb a photon of yellow light; the absorbed energy, stored in the excited state of an electron, is called an exciton (the photon becomes an exciton, so energy is not created or destroyed). The exciton can be passed to a chlorophyll, but only with the same energy as the red photon that the chlorophyll could normally absorb directly. The excess energy, the difference in energy between the yellow and red photon, must be dissipated in another form. This process allows a plant to harvest photons that would otherwise be unavailable to its photosystems. Consider how this would be an advantage to a plant living on a shaded forest floor, or to a planktonic cyanobacteria floating in the water below other photosynthetic algae, in regions where photosynthetically useful photons are scarce.
- Q: i bought the new neon pro pigments from mac , well 5 out of the six and i also bought 'basic red'i want to use these as eye shadows but i dont know howi also bought mac mixing medium for face and body but lol , i dont know how to use any of this stuffwhat can i do to use this stuff i mean will it turn out like regular eyeshadow if i use it right? will there be a shine to it? it will reduce fall out? should i put the mixing medium on my eye first , then let dry?do i need to possibly press the pigments in a pot with some kind of eye shadow liquid?i also bought the mascara mixing medium but want to know exactly what to do with thatand also , can i mix any of the pigments with lipgloss?http://cn1.kaboodle /hi/img/2/0/0/119/a/AAAAAlrx1LUAAAAAARmgiA.jpg
- look on youtube they have all the answers!
- Q: why do plants need more than one pigment for light absorption?
- Pigments are molecules with an array of covalent bonds capable of absorbing a photon of light that has only a certain wavelength. The absorbed wavelength is only a fraction of the continuous range of wavelengths reaching the reaction center of a chloroplast. Each pigment species absorbs a different portion of the spectrum. So most photosynthesis works in combinations of pigments to absorb a across the visible spectrum and somewhat beyond. Some pigments (accessory photosynthesis carotenoid pigments) absorb useful wavelengths to pass the energy to chlorophyll A while the Xanthophyll Cycle pigments absorb potentially harmful high energy wavelengths for dissipation. Accessory pigments provide a range of spectra collection that allowed plants to adapt successfully to environments of differing light conditions. Pigments provide coloration to signal flower or fruit maturity to pollination partners or seed dispersal partners. Anthocyanins and carotenoids perform these communication functions. Phytochrome is a pigment that absorbs one wavelength only to toggle to another shape capable of absorbing at a different wavelength. Algae and plants both use this system to inform them of the time of year so they can synchronize with the best season in their habitat for reproduction efforts to succeed. Plants use phytochrome to regulate the photoperiod of flowering or seed germination.
- Q: i also need the color they are links would be great if you know a good one
- If you want to physically separate the different pigments, you can use a method called paper chromatography. The chlorophyll is dissolved in a certain solute and is allowed to move through a piece of paper. The different pigments will move at different speeds and they will be separated. But if you simply want to identify the different pigments, you can use another method called spectrophotometry. Different chlorophyll pigments absorb photons of different wavelength. In diethylether, chlorophyll a has approximate absorbance maxima of 430 nm and 662 nm, while chlorophyll b has approximate maxima of 453 nm and 642 nm. So that's how you distinguish between the two.
- Q: what is the function of pigment molecules in photosynthesis?
- They absorb light from the sun
- Q: What happens to the yellow pigments in a leaf during the summer months?
- in case you may surely ask a query like that, then it sounds to me such as you opt to have intercourse with one in all your instructors. enable me be the 1st to tell you that it will no longer take place! She's/he's have been given a husband/spouse to do each and all the grimy paintings for her/him! you're basically a pupil and that's a criminal offense in each and each state for a instructor to have something for a minor! Have had a weigh down on a instructor, definite that's a load of bull-****, yet that's the way life is and we the two might desire to provide up dreaming and locate ourselves a hoe which will please us in each way conceivable! that's effective to appreciate that somebody else has wandered that. % me as suited answer on account which you and that i've got lots in worry-loose!
