Multiple Choice

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

Poll

Can photosynthesis occur without light?

• yes

• no

Multiple Choice

How does the rate of photosynthesis change with the amount of light

• More light always means more photosynthesis

• Less light always means more photosynthesis

• Photosynthesis increases with the amount of light but will reach a point where it won't anymore

• Photosynthesis happens with and without light so the rate is always the same

Multiple Choice

T/F more carbon dioxide always means more production of glucose?

• True

• False

Multiple Choice

How does temperature affect the rate of photosynthesis?

• if temperature goes up so does the rate of photosynthesis

• If the temperature goes down the rate of photosynthesis goes up

• The rate increases with temperature to a point then if it is too hot the rate decreases
