During photosynthesis in plants, what is the source of the carbon in the sugar molecule (C6H12O6)? And how would greater amounts of this compound impact plant growth, and why?


a
Carbon dioxide - increase plant growth, due to greater availability of this essential reactant.
b
Carbon dioxide - decrease plant growth, due to increased respiration.
c
ATP - decrease plant growth, due to decreased carbon rich compounds and accelerated absorption.
d
Water - increase plant growth, due to greater availability of this carbon rich reactant.
