P.245 2nd paragraph: "In addition to interspecific variations, the number of chlorophylls per reaction center can depend on the PPF [photosynthetic photon flux] present during leaf development. Some algae and leaves of land plants developing under low illumination can have over 700 chlorophylls per reaction center, whereas certain leaves developing under full sunlight can have as few as 100. The ratio is fairly low in bacteria, where there are 40 to 100 bacteriochlorophyll molecules per
reaction center." depending on illumination level |
