• To absorb nutrients from the soil

• To produce carbon dioxide

What is the green-colored chemical found in chloroplasts that assists in photosynthesis?

• Hemoglobin

• Melanin

• Chlorophyll

• Keratin

Which of the following is the correct chemical equation for photosynthesis?

• 6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
