In 1932, Researchers Emerson and Arnold Showed That the Rate

In 1932, researchers Emerson and Arnold showed that the rate of photosynthesis saturated at a lower light intensity than expected for the number of individual chlorophyll molecules. From this observation they determined

A) that high light intensities destroyed most pigment molecules
B) that pigments were clustered in photosystems and they were measuring saturation of pigments in reaction centers
C) that plants must be able to fix carbon before their pigments can absorb light
D) that they had overestimated the number of chlorophyll molecules present in their test organism
