21. What is an example of a
lab experiment that shows the
variation of the
photosynthesis efficiency in
relation to different photic
energy frequencies to which
the reaction is exposed? Was
it expected that green light
frequency favoured the
reaction?

The experiment: Plants same species

Chlorophyll is because it reflects
green light frequency, .e., it does

light does favour photosynthesis
