Chlorophylls (Chl) play pivotal roles in energy capture, transfer and charge separation in photosynthesis. Among Chls functioning in oxygenic photosynthesis, Chlis the most red-shifted type first found in a cyanobacterium. The location and function of Chlin photosystems are not clear. Here we ...
Photosynthesis occurs ineukaryotic cellstructures called chloroplasts. A chloroplast is a type ofplant cellorganelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production. A chloroplast contains a green pigment calledchlorophyll, which absorbs light energy for...
which store energy and help plants convert light energy into food. Chloroplasts contain pigmentation in the forms of chlorophyll a and chlorophyll b, which help absorb light that photosynthesis needs in order to occur. Chlorophyll
At the early embryogenesis embryos contain pregranal plastids which are then differentiate into photosynthetically active chloroplasts containing chlorophylls (Chl) and carotenoids. The main function of chloroplasts in seeds is not associated with CO2 fixation but with generation of NADPH and ATP, which...
Replication of the key processes in photosynthesis for the generation of solar energy conversion technologies has principally involved the synthesis of materials capable of efficiently collecting light energy, transferring energy, separating charges, and directing charge transport to catalytic centers for fuel...

In photosynthesis, light-harvesting chlorophyll molecules are shunted between photosystems by phosphorylation of the protein to which they are bound. An anchor for the phosphorylated chlorophyll–protein complex has now been identified in the reaction centre of chloroplast photosystem I. This finding supp...

Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis. Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. In plants, chloroplasts
Chlorophyll is a green pigment found in all plants. This green pigment is not only responsible for giving plants their green color, but also aids...
