- Q: I need to find powdered paint or pigment that I can throw, for some photographs.Preferably cheap, and that wouldn't stain skin.I've looked into powder paint, though this tends to stain skin for about a week.Thanks :)
- Smash up sidewalk chalk.
- Q: Why do algae contain pigments other than just chlorophyll?
- To use other wavelengths to perform photosynthesis.
- Q: Explain why plants need a variety of pigments to carry out photosynthesis?
- flora must be conscious of distinctive wavelengths of light which each and each and each soak up terrific at a definite pigment. this would enable the main potential to be transfered to the plant with a vast spectrum of light.
- 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: i was thinking of this all day long and then i thought of posting this question for you to help me sort it out
- 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. NOT the other war around. :) :)
- 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: pigment: its color (to our eyes) what color of light it absorbsChl a Chl bCartenoidsany right answers would bbe greatly appreicated thanks soo muchhh
- pigment: .... reflected color to eyes .. what color of light it absorbs Chl a reflects green spectra between the blue and red absorption peaks. Some is absorbed at blue 450nm but most absorbed at red 680 - 700nm. Chl b reflects green spectra between the blue and red absorption peaks with a difference in which peak is stronger. Most is absorbed at blue 470 but also some at blue 430 and red 640 nm. Cartenoids reflect yellow, orange, or red and absorbs blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm. Xanthophylls are a common sub class of the carotenoid pigment group. Beta-carotene absorbs most strongly between 400-500 nm.
- 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: what is one reason why plants have accessory pigment molecules like chlorophyll b and carotenoids?
- Chlorophyll actually speaking does'nt give the green color to the plant.It reflects the green wavelength and hence the green color.There are other pigments present in the leaf like chlorophyll a , chlorophyll b,c,d and e.Chlorophyll a is the primary pigment.It reflects the green,red and blue wavelength.It consitutes the reaction center in the chloroplasts which absorbs all the light incident on the leaf which in turn facilitates photosynthesis.Then there is Xanthophyll and carotene.Xanthophyll is orange yellow in color.Carotene is orange in color.Xanthophyll and Carotene are called as the accessory pigments present in the leaf.They reflect the blue, red and violet wavelength.I hope this info is sufficient.
