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:Oil paint: what's the pigment, binder, and vehicle?: Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.

Q:Why is it important for a plant to have more pigments than just chlorophyll?: If the plant only has chlorophyll, it is only able to absorb and use the wavelengths of light that correspond to chlorophyll, which is really limiting. Having other pigments allows it to use more wavelengths of light, which is more efficient.

Q:Your classmate suggests that chlorophyll is not the only pigment contained in plant cells. Is your classmate c: There are carotinoids there too. The yellow, orange and red we see in leaves before they drop. Masked by chlorophyll until that production stops.

Q:I want to do some work with native american indigenous pigments.?: Pigments from the past came from rocks, minerals, plants, and other natural materials. Those things are all still available. You can take classes at some universities that teach how to make your own paints, or dry pigments. For native American pigments, you have to research which tribe used which colors. To be totally authentic you could visit the tribe of your choice and see if you can learn from them. Sticking to your own zip code will not net you much, usually.

Q:What is the difference between primary and accessory pigments?: primary pigments are the ones the electron involved in photosyn. goes to AFTER hitting the accessory pigs. in order to be sent to the electron transport chain. this is the case with photosystem 2 AND 1, they look like this: kvhs.nbed.nb.ca/gallant/biology/photosystem.jpg the green are accessory, and the blue is where the primary are. hope that helps...im a little rusty since i took AP bio last year.

Q:what is pigment color powder?: itz for ur beautifing ur skin.

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:Are pigments the same as tannins?: Yes, tannins are pigments but they aren't really the main plant pigment. Plant pigments usually refer to photosynthetic pigments (chlorophyll, carotenoids, etc.). These photosynthetic pigments give the leaves their green color (or yellow/orange in the fall). Tannins are non-photosynthetic phytochemical (involved in plant metabolism and internal functioning), but they are also a pigment. Tannins (and lignins) are brown. This is was gives dead leaves and wood their color. Tannins also leach out of the leaves when soaked in water (same process as brewing a cup of tea). So tannins are pigments when they leach out of leaves and stain water (or other things) brown, but they are not photosynthetic plant pigments. In other words, it depends on what context you are calling a tannin a pigment. In a live plant they are not a pigment (judgment call here). In a dead leaf or when they leach out of a leaf they are a pigment.
