6CO₂+ 6H₂O ?

• 6CO₂ + 6H₂O + 2 ATP, photosynthesis

• C₆H₁₂O₆ + 6O₂ + 0 ATP, photosynthesis

• 6CO₂ + 6H₂O + 2 ATP, cellular respiration

• 
  C₆H₁₂O₆ + 6O₂ + 0 ATP, cellular respiration

Multiple Choice

How is the energy generated during photosynthesis stored?

• in the chemical bonds of sugar molecules

• as DNA molecules

• in RNA strands within ribosomes

• as phospholipids

Multiple Choice

A plant is placed in a completely dark closet. How will the production of glucose most likely change?

• It will increase because the plant will have additional CO₂ available for respiration.

• 
  It will increase because the rate of photosynthesis will increase.

• It will decrease because there is no light available for respiration.

• It will decrease because there is no light available for photosynthesis.

Multiple Choice

The diagram below shows a plant in a pot with a clear glass dome completely enclosing the plant. The plant is sitting near a glass window. The plant gets water by soaking it up from the water pan underneath it. Every day, water is added to the pan and the plant height is measured without removing the glass dome that encloses the plant.

  carbon dioxide

• sunlight

• 
  oxygen

• water
