The action spectrum of photosynthesis shows a high light absorption for violet/blue and orange/red and a low absorption for green/yellow. If we were to set up an experiment where narrow bands of unicolored light were 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 at violet/blue and orange/red and a trough at yellow/green B. a descending line because ultraviolet light has more energy than infrared C. perfectly flat because many wavelengths are used by chlorophyll D. exactly inverted from the action spectrum with a peak for yellow/green E. There is no way to guess without actually running the experiment.
