Unit 3 Photosynthesis SAC?

[kerry.j]

Has anyone seen Question 3, d) (short answer), on the 2009 mid year exam?
Could someone explain the question as i'm so lost on how the answer comes to that conclusion.

In addition, Question 17 of the MC, on the 2010 mid year exam.
How are we suppose to know that?!

For the second one, I think students are often taught that red and blue light are most effective for photosynthesis. Between red and blue, some sources say that red light allows for slightly more effective photosynthesis than blue light. However, it would really depend on the plant and the pigments it contains, wouldn't it?

Well anti-freeze substances in plants lower the freeIng point of the fluid found in cells, in cold arctic climates. So it would have to be an anti-freeze substance?!
