Which is a definition for photosynthesis?

• Releasing energy from nutrients

• The breaking down of large insoluble molecules into small soluble molecules

• The process by which plants make carbohydrates from raw materials using energy from light

• The movement of particles from a high concentration to a low concentration

Which is the word equation for photosynthesis?

• glucose + oxygen -> carbon dioxide + water

• methane + oxygen -> carbon dioxide + water

• glucose + carbon dioxide -> oxygen + water

• carbon dioxide + water -> oxygen + glucose

State the balanced symbol equation for photosynthesis

• CO₂ + H₂O -> C₆H₁₂O₆ + O₂

• C₆H₁₂O₆ + 6O₂ -> 6CO₂ + 6H₂O
