ACarbon dioxide (CO₂)
BGlucose breakdown
CWater (H₂O) — photolysis
DChlorophyll itself
Question 2
Which plant hormone controls phototropism (bending toward light)?
AGibberellin
BAbscisic acid (ABA)
CAuxin (IAA)
DCytokinin
Question 3
The overall equation for photosynthesis is:
AC₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy
B6CO₂ + 6O₂ + Light → C₆H₁₂O₆ + H₂O
C6CO₂ + 6H₂O + Light → C₆H₁₂O₆ + 6O₂
D6H₂O + Light → C₆H₁₂O₆ + CO₂
