Q:What pigments take part in photosynthesis?
Photosynthesis in plants is dependent upon capturing light energy in the pigment chlorophyll.This chlorophyll resides mostly in the chloroplasts and gives leaves their green color. The range of light absorption in leaves is extended by some accessory pigments such as the carotenoids, but does not cover the entire visible range - that would make the leaves black! Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light. They also have a red pigment called phycoerythrin that absorbs green light and extends the range of photosynthesis. The red pigment lycopene is found in vegetables. Some red algae are in fact nearly black, so that increases their photosynthetic efficiency. Brown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range.
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!
Q:what are the accessory pigments in plant photosynthesis?
The photosynthetic pigments are of two types, primary pigments and accessory pigments. The accessory pigments pass the emitted electrons to the primary pigments. Electrons are then emitted from the primary pigments and it is these that drive the photosynthetic process. The two primary pigments are both forms of chlorophyll a, called P690 and P700 (absorbing light best at 690 and 700 nm wavelengths, respectively). The accessory pigments include other forms of chlorophyll a, chlorophyll b and carotenoids. The light energy trapping systems of the plant are called photosystem I and photosystem II. Energy capture traps of photosystems I and II (in the quantosomes) light energy The quantosomes are regularly spaced particles embedded in the thylakoids, and are either large or small. It is probable that the large quantosomes contain photosystem II and reaction centre II and the small quantosomes contain photosystem I and reaction centre I.
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.
Q:If they are not the same, then what is the difference? Please help me out here.
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.
Q:Does anyone know of a way to change the color of your iris' permanently?I've been researching for a while, and have not been able to find anything! I already know about newcoloriris (surgery), but that had loads of side effects. I already know about contacts (ive had them on and off for a while).I don't see how with all the science and technology in the world, there's no way to simply lighten your eye color. We can literally dye our skin, we can tattoo our eyeballs, we can do almost ANYTHING in the world today. So, how has nobody discovered a way to change eye color.?I'm aware that blue/light eyes are a result of low melanin production, But i don't understand how there's no known way to reduce the overproduction of melanin in darker/brown eyed people.It's really frustrating. If anyone knows any websites, doctors, or scientists currently working on a way to do this, please let me know! Or if you know of a new way someone has come up with, please let me know!lt;3 THANKSSSS
Hurrah, that's what I was looking for! Thanks to author of this question.

Q:what roles do pigments have in energy transfer?
Pigments okorder /... When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. If the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the photosynthetic reaction center from the pigment array, to split water and take back an electron. Meanwhile the chlorophyll's electron passes to the electron transport chain to begin oxidative phophorylation.
