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

Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis? 

• The light-dependent stage
• The light-independent stage (The Calvin Cycle)
• The electron transport chain
• ATP formation

Where does the oxygen come from that is released during photosynthesis?

• CO₂ (carbon dioxide is split)

• C₆H₁₂O₆ (glucose is split)

• H₂O (water is split)

• The air (it is already there)

Why are the palisade cells at the top of the leaf?

• To get more water

• To absorb more sunlight

• To get more carbon dioxide

• To get more oxygen

Why do the stomata open and close?

• To control the amount of water loss

• To control the release of oxygen

• To control the amount of carbon dioxide absorbed

• To help get more sunlight
