Biology Photosynthesis in Higher Plants Skill Builder Single Correct MCQ
Published on: August 21, 2026

Thomas Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of the algal filament to different wavelength of light. He added aerobic bacteria and found that these bacteria congregated in the areas illuminated by red and blue light. If you run the same experiment without passing light through a prism, what would you predict?

A
There would be no difference in results
B
The number of bacteria would decrease along the entire length of the filament
C
The bacteria would be relatively evenly distributed along the length of the filament
D
The number of bacteria would increase along the entire length of the filament

The correct answer is:

                    

If the same experiment is performed without passing light through a prism then the bacteria would be relatively evenly distributed. This is because bacteria congregated to where the most photosynthesis happens. In the absence of light, there is no photosynthesis and thus the bacteria will spread out evenly.
