4. Which can be said about blue light vs. yellow light?
a)
A Blue light has a short wavelength and is effective for plant absorption
b)
B Yellow light is just about the best color of light for plant absorption
c)
C Yellow light has the shortest wavelength but it cannot be absorbed effectively

11. Where does the "cycle" part of Calvin Cycle come from?
a)
A Melvin Calvin loved to ride his bicycle
b)
B The cycle happens from regeneration of RuBP from five PGAL molecules
c)
C It comes from the carbon dioxide that is allowed into the plant from the atmosphere

15. Five of the same species of green plants are exposed to red, green, blue, yellow and violet light. Which of the following is true?
a)
A The plant under green light would absorb green light
b)
B The plant under blue light would photosynthesize well
c)
C Yellow and green are the best colors for plant growth.

13. Why do we balance the photosynthesis equation?
a)
A Because it looks nicer
b)
B Because scientists like working with numbers
c)
