Which is the correct formula for photosynthesis?

• 6CO₂ + 6H₂O +sunlight --> C₆H₁₂O₆ + 6O₂

• 6O₂ + 6H₂O + Sunlight --> C₆H₁₂O₆ + 6CO₂

• C₆H₁₂O₆ + 6O₂ --> (in sunlight) 6CO₂ + 6H₂O

• 6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂ + sunlight

Why do plants need sunlight for photosynthesis?

• The light creates heat needed for photosynthesis to occur

• The light provides the energy needed to power photosynthesis

• Plants can't absorb carbon dioxide in darkness

• Plants can't absorb water in darkness
