In this experiment, you will measure the rate of photosynthesis
in isolated chloroplasts using the dye 2,6-dichloroindophenol
(DPIP). The transfer of electrons during the light-dependent
reaction results in the production of H+. This H+ ion can reduce
DPIP, changing its color from blue to clear. The color can be
quantitatively measured with a spectrophotometer. However, in this
experiment, you will qualitatively analyze your data.
Write a detailed conclusion for your experiment. How did light
