Cellular Energy

What are the products of photosynthesis?

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

What molecule absorbs sunlight for photosynthesis?

• chloroplast
• thylakoid
• grana
• chlorophyll

What is the name of the simple sugar that is produced in photosynthesis?

• Sucrose
• Dextrose
• Glucose
• Lactose

Why do plants go through photosynthesis?

• To make food for us
• To make food for themselves
• They're bored and have nothing else to do

Which of the following best describes photosynthesis?

• Photosynthesis converts light energy into chemical energy.
• Photosynthesis produces carbohydrates.
• Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis.
• Plants use chlorophyll, water, and carbon dioxide to make sugar.

Which gas is removed from the atmosphere during photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide

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 

What gas is released by plants during photosynthesis?

• sulfur
• carbon dioxide
• oxygen
• hydrogen

How can photosynthesis be related to cellular respiration?

• What's produced (made) by one is needed (the reactants) for the other
• They both produce the same products
• They both have the same reactants (need the same things)
• These 2 processes have nothing in common

Why is photosynthesis important?

• creates oxygen for animals to breath
• creates food/energy for animals  to use
• creates food for plants to use
• all of these are correct
