Each pigment can absorb different wavelengths of light, which allows the plant to absorb any light that passes through the taller trees. (credit: Jason Hollinger) Query
Oct 27, 2024· The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.
Earth absorbs about 47 percent of total insolation, and the atmosphere about 19 percent. About 34 percent is reflected back into space—23 percent by clouds, 9 percent by the atmosphere, and 2 percent by Earth''s surface. Plants Science and Mathematics Society
Professor Gabriela S. Schlau-Cohen (center) and graduate students Raymundo Moya (left) and Wei Jia Chen worked with collaborators at the University of Verona, Italy, to develop a new understanding of the mechanisms by which plants reject excess energy they absorb from sunlight so it doesn''t harm key proteins.
