A researcher exposes a suspension of green algae that contain chlorophylls to different light sources with different wavelengths. Compared with a suspension of algae that is receiving white light, the algae exposed to artificial light from source 1 remains healthy but produces less oxygen and has a slower growth rate. The algae exposed to artificial light from source 2 stops to produce oxygen, and its growth is halted. Given your knowledge of chlorophylls, which of the following statements about the light sources is best supported by this observation?
a)Light source 1 provides only green wavelength light
b)Light source 2 provides only red wavelength light
c)Light source 1 provides only blue wavelength light
d)Light source 2 provides blue and red wavelength light
Homework Answers
b) Light source 2 provides only red wavelength light
Light source 2 acts as a source of light of red wavelength, as aresult of which they stop producing oxygen an dtheir growth is halted.
