(BIOS 100) 2024/2025 MIDTERM CELLS AND ORGANISMS
EXAM |VERIFIED 100%
This exam consists of 42 super easy questions distributed over six pages. Each question is worth
four points in the solo exam and one point in the group exam. Please check to see that all the
pages are present before you begin. Use a #2 pencil and bubble in all answers. Choose the best
answer for each question. Your score will be posted on the UIC Blackboard site as soon as they
are in. Only answers on the scantron will count, though (so be careful and don’t make mistakes
when bubbling in answers!) Make Sure you correctly bubble in your UIN! Good Luck!
1. Where would you expect to find the
greatest distribution of C4 plants?
A. Oregon forest
B. Kansas grassland
C. Indiana prairie
D. Maine coastline
E. Florida Everglades
2. Plants grown under which colors of light
would you expect to see the greatest photosynthetic rate?
A. Red & Yellow B. Green & Yellow C. Green & Blue D. Red & Blue
3. Everyone in this class should know that plants have a net intake of CO2 and a net output of O2.
What is molecular source of this O2 produced as a byproduct of photosynthesis?
A. CO2 B. Glucose C. H2O D. ATP E. None of the above
4. How many of the below growth conditions will show decreased rates of photorespiration in
plants when compared to plants grown under normal atmospheric conditions (oxygen at
20% and CO2 at 390 ppm)
I. Oxygen 10%, CO2 390 ppm IV. Oxygen 20%, CO2 600ppm
II. Oxygen 10%, CO2 600 ppm V. Oxygen 30%, CO2 200 ppm
III. Oxygen 20%, CO2 200ppm
A. None B. One C. Two D. Three E. Four
5. You measure the photosynthetic rate of two different species of plants under normal
environmental conditions. You then place them in a growth chamber with identical light,
water, and atmospheric conditions with the exception that the CO2 concentrations are
triple those of normal atmospheric levels. Plant Species A shows very little change in
photosynthetic rate while Plant Species B shows a marked increase in photosynthetic rate.
What conclusions could you draw about plant species A & B?
A. Species A & B are both C3 plants
B. Species A & B are both C4 plants
C. Species A is a C3 plant while Species B is a C4 plant
D. Species A is a C4 plant while Species B is a C3 plant
, 6. You take the same plants seen in question 5 and place them in another artificial environment.
This environment has normal levels of CO2, but the oxygen levels have been increased to
30%. How will this affect their photorespiration rate?
A. Species A & B will be largely unaffected by increases in oxygen concentration
B. Species A will show a great increase in photorespiration rate, Species B will not
C. Species B will show a great increase in photorespiration rate, Species A will not
D. Both Species A & B will show the same great increase in photorespiration rate
7. Which of the below can transport molecules and ions against their total concentration
gradient?
A. Diffusion B. Facilitated Diffusion C. Active Transport
D. A & B E. A & C
8. Which of the following statements (A-D) about the Na+/K+ pump is FALSE. If statements
A-D are true, then choose E.
A. The Na+/K+ pump has two configurations, one which can bind to Na+ and the other
which can bind to K+
B. One way to change configuration of the Na+/K+ pump is to phosphorylate it with the
phosphate group from ATP
C. The Na+/K+ pump transports three Na+ into the cell and two K+ out of the cell
D. The Na+/K+ pump is an example of an integral membrane antiport transport protein
E. All of the above statements about the Na+/K+ pump are TRUE
9. Which leaf below is the C3 leaf? B
10. What is the final electron acceptor in non-cyclic photophosphorylation?
A. Oxygen B. Water C. ATP
D. NADP E. Glucose
11. The Rubisco in a C4 plant is fundamentally different from the Rubisco in a C3 plant.
A. True B. False
