Question

Plant cells undergo photosynthesis to produce glucose, a usable form of chemical energy. The energy produced by plants becomes the base of an energy pyramid. Given the situation seen above, what reactant is missing in order for photosynthesis to occur

A) water 
B) ozone 
C) chlorophyll 
D) radiant energy

Answer 1
