Q:Plant Pigments And Biology?
Pigments in the reaction center work together to organize themselves in place, to protect the plant from injury from incidental light, and to absorb photons from the spectrum with each pigment catching its own portion of the incoming wavelengths. The accessory pigments catch and pass energy to chlorophyll a. Chlorophyll a is the specialist that plays the photon's electromagnetic energy into chemical. It splits water to release its electrons and hydrogen ions for use in the calvin cycle where glucose is manufactured. The goal is to fix energy into a usable organic form for the plant to live on.
Q:what is the role of photosynthetic pigments in plants?
Well photosynthetic pigments has to do with the different component of light (i.e. the colors - ROYGBIV) and their specific wavelenght. Photosynthetic pigments based on their colors can capture the energy from that wavelenght. For example fucoxanthin can capture the brown color of the light just like phycocyanin can capture the blue color of the light. These photosynthetic pigments are usually the accessory pigments of Chlorophyll A which is the main pigments of most of the photosynthetic organisms in the earth.
Q:does photosythesis requier pigment moulecuels?
Pigments are needed, because they absorb the energy from the light. Different chlorophylls absorb different wavelengths. When pigment absorbs the photon, it releases an electron, which is used in photosynthesis as energy. Without pigment the light would just past through or reflect and no energy would be left to the cell to be turned into sugar.
Q:How many pigments does grass reflect?
Pigments are the colors that make grass look green. They are the pigments that do photosynthesis. Grass looks green because it reflects green light. It reflects the wavelengths of light that have the frequency of green light. Grass has other pigments that we do not see through the chlorophyll, but it is the light that is reflected.
Q:Can someone describe the role of accessory pigments in photosynthesis?
help the primary pigments gather sunlight and adds color to the plant
Q:What are pigments?
Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear colorful. Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths.
Q:whats pigment?
It's a small plant that pigs love to eat. It's sort of like catnip, except that pigs love it (cats won't touch it). It is related to the catnip and mint family of plants.
Q:What is the difference between primary and accessory pigments?
Color. Chlorophyll a is light green. The accessory pigments, chlorophyll b is olive green, the xanthophylls are yellow/brown, and the carotenes are red.
Q:M.A.C pigments question!?
Buying okorder.com/... Good luck dear! If all else fails, I suggest going on specktra.net and asking on there. It's a MAC and make-up community forum and they're extremely helpful and informative when it comes to anything MAC!
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.
