Question: Which process is most directly driven by light energy?

A. creation of a pH gradient by pumping protonsB. carbon fixation in the stroma C. reduction of NADP+ molecules D. removal of electrons from chlorophyll molecules E. ATP synthesis

Question: How is photosynthesis similar in C4 plants and CAM plants?    

A. in both cases, only photosystem I is used. B. both plants make sugar without Calvin cycle. C. in both, rubisco is not used to fix carbon initially. D. both plants make most of their sugar in the dark. E. in both, thylakoids are not involved in PHS.

Short Experiment:

Growing radishes from seed

Page 13: Announcements Stand up if full group, Ch.10, play? Write researcher for mutant DNA yet? Interview with Prof by 13 th “Verbal finals” begin when? How do.

Biology Radish ProblemWeighed out 3 batches of radish seeds (each 1.5

g).Experimental treatments:

» 1. Seeds not moistened (dry) placed in LIGHT » 2. Seeds on moistened paper towels in LIGHT» 3. Seeds on moistened paper towels in DARK

After 1 week, all plant material was dried & weighed.

• TASK: Predict the (dried) biomass of the plant material in the various treatments.

Predict the final (dried) bio-mass [increase/decrease/no change]

A. no change – increase – no changeB. increase – increase – increaseC. increase – decrease – no changeD. decrease – increase – decreaseE. None of the above are correct

Results: Weight of Radish Seedlings

1.46 g 1.63 g 1.20 g

How do you explain the results?(Remember all treatments started as 1.5g).
