4. Corn planted in a field that has been previously planted with legumes and then plowed under is likely to be a.Less productive because legumes remove phosphorus from the soil. b.More productive because bacteria living on the roots of legumes fix nitrogen in the soil. c.More productive because nitrogen fixing bacteria help to keep away pests. d.Less productive because the legumes have already taken all the nitrogen, carbon and phosphorus from the soil.

20. Which of the following is not a step in the light- dependent reactions? a.High energy electrons move through the electron transport chain. b.Pigments in the thylakoid absorb light. c.AT synthase allows H+ ions to pass through the thylakoid membrane. d.ATP and NADPH are used to produce high energy sugars.
21. Why does the inside of the thylakoid membrane become positively charged during the light- dependent reactions? a.H+ ions are released as water splits. b.ATP synthase allows H+ ions to pass through the membrane c.ATP synthase produces ATP from ADP. d.Carbon dioxide builds up in the stroma.

24. How does the Calvin cycle differ from the light-dependent reactions? a.It takes place in the stroma b.It takes place in chloroplasts c.It requires light d.It takes place in the thylakoid
25. If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars? a.More sugars will be produced b.No sugars will be produced c.The same number of sugars will be produced by without carbon dioxide d.Carbon dioxide does not affect the production of high-energy sugars in plants.
