A researcher illuminated a filament of cyanobacteria with light that passed through a prism, thus exposing different segments of cyanobacteria to different wavelengths of light. He found that the bacteria in the green light changed in color from green to red after multiple weeks of exposure but were still reproducing at the same rate. What can you conclude about the change in pigmentation of the cyanobacteria exposed to green light? 1.) More chlorophyll a was produced in response to the green light exposure

2.) The cyanobacteria were dying and were changing color in response

3.) Red light instead of green light was being absorbed by the chloroplasts

4.) More red photosynthesis pigments were produced to absorb green light
