Background Photosynthesis

• Chemical Reaction in Living Things
• Energy Conversion
• Reactants (substances needed)
• Products (new substances created)

• Reactants of Photosynthesis
• Carbon dioxide (CO2)
• Water (H2O)
• Products of Photosynthesis
• Glucose (C6H12O6)
• Oxygen (O2)

• Energy of Photosynthesis
• Energy of Sunlight to the energy of food (sugar)
• Light Energy to Chemical Energy
• Making Food From Sunlight
