Which of the following equations represents the overall chemical reaction for photosynthesis?
6O2+ 6H2O → C6H12O6+ 6O2
C6H12O6 + 6H2O→ 6O2+ 6O2
6CO2+ 6H2O→ C6H12O6+ 6O2
6O2 + 6H2O→ C6H12O6 + 6CO2
Why are plants usually green?
Because the chlorophyll reflects green light
Because the chlorophyll absorbs green light
Because the accessory pigments combine to make green
Because the accessory pigments only absorb green light
