What is the most correct equation for photosynthesis?
CO2 + H2O yields C6H12O2
6CO2 + 6H2O in the presence of light, yields C6H12O2
6CO + 6HO in the presence of light, yields CHO
6CO2 + 6H2O yields C6H12O2

What's special about C4 plants?
They allow carbon dioxide to enter at night, as they need to regulate photosynthetic activity
They include rice, orchids, and potatoes
They have no structural modifications to their cells
These plants fix carbon dioxide into four-carbon compounds instead of three-carbon molecules during the Calvin cycle
