Light harvesting among photosynthetic organisms

摘要: Examination of light absorption by photosynthetic tissues 156 specimens from 128 species chlorophyll a containing organisms, ranging single-celled cyanobacteria to trees, confirmed the existence universal law involving asymptotic increase in with increasing density. The concentration decreased as become thicker, thereby avoiding high areal density and inefficient absorption. Light per unit tissue weight was strongly, linearly related concentration, explaining lower growth rates higher requirements thick, compared thin organisms dominance shaded environments (...)
