RELATION BETWEEN QUANTITY OF CHLOROPHYLL AND CAPACITY FOR PHOTOSYNTHESIS

Abstract

During photosynthesis in flashing light under optimal external conditions, the ratio of moles of chlorophyll present to moles of CO2 reduced per flash is not a constant in Chlorella pyrenoidosa cells, but depends on conditions of previous growth, increasing sharply with age of culture and varying with color and intensity of culture illumination. Thus the maximum amt. of CO2 reducible per flash doea not appear to be directly related to the amt. of chlorophyll present, but depends on some other internal factor.
