Photosynthesis

What is the byproduct of photosynthesis released by plants through stomata (pores in leaves)?

• Water
• Oxygen
• Glucose
• Carbon dioxide

What is the full chemical equation of photosynthesis?

• 6CO2 + 6H20 + C6H12O6 + 6O2
• 6CO2 + 6H20 + Sunlight → C6H12O6 + 6H2O
• 6CO2 + 6H20 + Sunlight → C6H12O6 + 6O2
• 6CO2 + 6H20 + Sunlight → C6H12O6 + 6CO2

What is the role of cellulose in plants?
