Chl b, Chl c, and Chl f are considered to be accessory pigments found in antennae systems of photosynthetic organisms. They absorb energy and transfer it to the photosynthetic reaction center (RC), but do not participate in electron transport by the photosynthetic electron transport chain. ...
Plants and other photosynthetic organisms use chlorophyll to absorb light (usually solar energy) and convert it into chemical energy. Chlorophyll strongly absorbs blue light and also some red light. It poorly absorbs green (reflects it), which is why chlorophyll-rich leaves and algaeappear green. ...
Photosynthetic pigments usually have different colors, and they absorb light of different wavelengths depending on the color. Chlorophyll is unique to other pigments in that it absorbs light rays of a particular wavelength that have enough energy to build tissues. Chlorophylls inplantsare present in ...
For land plants, the main chlorophyll pigments are chlorophyll a and b. Chlorophyll a, however, is the type of chlorophyll that can convert light energy and thus participates directly in the light reaction of photosynthesis. Chlorophyll b, in contrast, can absorb light energy but eventually relays...
(cyanobacteria, algae and higher plants) primarily absorb solar energy in the visible spectral (400700 nm) region by use of various chlorophylls, while anoxygenic phototrophs are bacteria, which can absorb infrared wavelengths (>7001100 nm) by use of different bacteriochlorophylls (Overmann and ...
which catalyzes the final step in the production of capsanthin and capsorubin. Recessive alleles of other nuclear gene(s) reduce the quantities of pigments in the fruits, but we do not know where or what these blocks to pigment synthesis may be. Chocolate-brown fruits, such as those used ...

Well, in autumn, a whole lot of other chemical constituents of the leaf break down as well.I don’t mean they are totally destroyed ‘cause actually they break down into other different chemicals that the tree can reabsorb from the leaves and reuse later.(听力 托福-12)您的浏览器不支持 ...
In higher plants the chlorophylls and the above-mentioned pigments are contained in lipoprotein bodies, the plastids. See Carotenoid, Cell plastids, Photosynthesis Chlorophyll molecules have three functions: They serve as antennae to absorb light quanta; they transmit this energy from one chlorophyll ...
and orange-red light. Chlorophyl b is also involved in photosynthesis and absorbs primarily blue light. There are other forms of chlorophyl such as Chlorophyll c1, c2, c3 which are accessory pigments. Recently, Chlorophyll f was announced to be present in cyanobacteria and other oxygenic ...
