Wavelength of light (nm)
What wavelength of light in the figure is most effective in driving photosynthesis?
A) 420 nm
B) 575 nm
C) 625 nm
D) 730 nm
9) Theodor W. Engelmann illuminated a filament of algae with light that passed through a pri
thus exposing different segments of algae to different wavelengths of light. He added aerobic
bacteria and then noted in which areas the bacteria congregated. He noted that the largest grou
were found in the areas illuminated by the red and blue light. What did Engelmann conclude
about the congregation of bacteria in the red and blue areas?
A) Bacteria congregated in these areas due to an increase in the temperature of the red and blu-
light.
B) Bacteria congregated in these areas because these areas had the most oxygen being released
C) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than
other wavelengths.
D) Bacteria congregated in these areas due to an increase in the temperature caused by an
increase in photosynthesis.
