Terms and sample questions for Exam 3. Carnivorous plants will be on Exam 4.
Each set of notes has a review list at the end of it. Try writing answers to all of the questions given in those lists. In addition to the topics on the list, you should also know important terms. Use the following list to supplement the other lists. The following includes most (hopefully all) of the terms that go with the material covered for your third exam. For many of the terms, it’s not just a matter of being able to define them. You need to be able to describe their role in a process or structure and distinguish between similar terms.

be able to list all of the essential elements and give at least one metabolic function for each macronutrient symbiosis mycorrhizae |
Some seeds are dormant until stratification takes place. What is
stratification? Why is it an important dormancy mechanism?
Give one example of each of the following types of fruit:
berry =
drupe =
pome =
legume =
Be able to recognize the parts of a seed.
Why is stepwise conversion of sugar to CO2 important?
What is the importance of generating carbon intermediates during glycolysis
and the Krebs cycle?
What are thermogenic plants? How do they generate more heat then non-thermogenic
plants? What do thermogenic plants sacrifice in order to produce heat
instead?
Under what environmental conditions is CAM photosynthesis an advantage?
Why?
Under what environmental conditions is C4 photosynthesis an advantage? Why?
Nitrogen cycle: ammonification, nitrification, nitrogen fixation
(symbiotic and free-living), denitrification, N assimilation by plants
What roles do bacteria play in the different steps of the nitrogen cycle? In
particular, address their roles in nitrogen fixation, ammonification,
nitrification, and denitrification.
Be able to give at least one function of each of the macronutrients.
The exam material includes Branching Out, the video on seed dispersal.

D. water (H2O) during the Calvin cycle
Plant which engage in C4 photosynthesis
A. have
Kranz anatomy B. lack photorespiration C. lack the Calvin cycle D. A and B E. A and C
Photosynthesis and aerobic respiration have all
of the following in common EXCEPT
A. rely on existing molecules in cells to carry
out the energy conversion reactions
B. are processes that store energy in the form of sugar
C. use organelles with complex internal membrane systems
Which of the following essential elements is NOT obtained by plants as a soil
mineral?
A. carbon (C) B. sulfur (S) C.
calcium (Ca) D. boron (B)
E. none of the above, as A, B, C, and D are all obtained as soil minerals
In symbiotic nitrogen fixation, the fixation reaction is performed by
A. legumes B. mycorrhizae C.
Rhizobium bacteria

A. heterotrophs B. chemosynthetic autotrophs
C. photosynthetic autotrophs
