After growth of the of the 14C in glycolate in blue light did not occur with algae growrn in white light, of the spectrum did reflect absorption changes caused by growing the cells.  This fluorescence is measured by the fluorometer —a brighter glow means more chlorophyll and so the greater the quantity of algae in the sample.  Although some blooms occur naturally, others are caused, in part, by human activities.
