1.
potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?
a)
The plant will grow faster because it is sheltered from the wind.
b)
The plant will die because it does not have oxygen for photosynthesis.
c)
The plant will die because it does not have carbon dioxide for photosynthesis
d)
The plant will grow at a slower rate because it requires more water.
2.
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?
a)
Only species Y is aerobic.
b)
Only species Y is anaerobic
c)
Both species X and Y are aerobic.
d)
Both species X and Y are anaerobic.
3.
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
a)
As the cells run out of oxygen they switch to anaerobic respiration (fermentation), which allows the cell to make small amounts of ATP in the absence of oxygen.
b)
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
c)
The cells will never run out of oxygen if the weightlifter is breathing.
d)
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
4.
In which way are photosynthesis and cellular respiration different?
a)
Cellular respiration stores ATP, while photosynthesis releases ATP.
b)
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
c)
Photosynthesis releases energy, while cellular respiration stores energy.
d)
Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.
5.
The diagram shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.
Which statement describes how photosynthesis and cellular respiration are interrelated?
Which statement describes how photosynthesis and cellular respiration are interrelated?
a)
Oxygen is produced during cellular respiration and stored during photosynthesis.
b)
Carbon dioxide and water released by cellular respiration are used in photosynthesis.
c)
Photosynthesis releases the energy that is stored during the process of cellular respiration.
d)
Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.
6.
Which of the following equations best represents photosynthesis?
a)
C + O2 + H2O = CO2 +HOH
b)
6CO2 + 6H2O = C6H12O6 + 6O2
c)
6C + 6 H2O = C6H12O6
d)
C6H12O6 = 6CO2 + 6H2O
7.
What is the correct equation for cellular respiration?
a)
6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy
b)
6O2 + C6H12O6 + Energy -> 6CO2 + 6H2O
c)
6CO2 + 6H2O -> 6O2 + C6H12O6 + Energy
d)
6CO2 + 6H2O + Energy -> 6O2 + C6H12O6

9.
How are cellular respiration and photosynthesis related, in terms of energy?
a)
The energy captured in photosynthesis is used to power cellular respiration.
b)
The energy transformed in cellular respiration is used to power photosynthesis.
c)
Photosynthesis and respiration perform the same task in terms of energy transformation
d)
Energy is not involved in either photosynthesis or cellular respiration.
10.
Two test tubes were filled with a solution of bromthymol blue. A student exhaled through a straw into each tube, and the bromthymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color?
a)
Oxygen was produced by photosynthesis.
b)
Carbon dioxide was removed by photosynthesis.
c)
Carbon dioxide was produced by respiration.
d)
Oxygen was removed by respiration.
