What did Engelmann conclude about the congregation of bacteria in the red and blue areas?
Answer: Option C
:
C
Engelmann used oxygen loving bacteria to grow on the algae. The bacteria congregating in the region of the red and blue light indicated that there was more oxygen being produced in these areas, indicating there was more photosynthetic activity in these areas. Thus Engelmann concluded that the red and blue light of the visible spectrum generate more photosynthetic activity than other parts of the visible spectrum.
