If carbon dioxide is removed from a plant's environment, what would you expect to happen to the plant's production of sugar (glucose)? (HINT: Think of what would happen if you removed an ingredient from a recipe!)

• MORE sugars will be produced
• The SAME NUMBER of sugars would be produced, but without Carbon Dioxide.
• FEWER will be produced
• the plant would not be affected in any way

Which of the following is the correct equation for PHOTOSYNTHESIS?

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