Which gas is removed from the atmosphere during photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide

What are the products of photosynthesis?

• water and carbon dioxide
• oxygen and glucose
• oxygen and carbon dioxide
• oxygen and water

Which organelle performs PHOTOSYNTHESIS?

• Chloroplast

• Leaf
• Cell membrane

The main source of energy for living things can be traced back to

• the earth

• Oxygen

• the sun

• Glucose

Chlorophyll absorbs a higher percentage of _____ and _______ light.

• purple and green
• red and blue
• black and orange
• yellow and green

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
