10. The action spectrum of photosynthesis shows a higher light absorption for violet/blue and orange/red and a lower absorption for green/yellow. If we were to set up an experiment where narrow bands of uni-colored lights where shown on an aquatic plant such as Elodea, and we counted the number of bubbles of oxygen produced as an indicator of photosynthetic rate, how would the graph appear?

a. just like the action spectrum with peaks (high) at violet/blue and orange/red and a trough (low) at green/yellow
b. exactly inverted from the action spectrum with a peak for green/yellow
c. flat because many wavelengths are used by chlorophyll
d. a descending line because ultraviolet has more energy than infrared
e. there is no way to tell without actually conducting the experiment
