Station 1: Absorption Spectrum for Chlorophyll
A pigment is a substance that absorbs light of particular wavelengths. Think of a pigment as a sponge
that soaks up all of the other colors of the spectrum except the one you see. A spectrophotometer is
an instrument that can be used to measure that amount of light absorbed by a pigment. The graph
below shows the percent of light energy absorbed for the different wavelengths (colors) of light. The
highest peaks represent colors that chlorophyll absorbs the most. Therefore, they are seen the least.

Station 3: Respiration VS. Photosynthesis
X-X-O
Using your knowledge of photosynthesis and respiration answer the following questions below to be
able to play the tic-tac-toe game with your partner. Each question you answer correct (flip over to
answer) it is your turn to put an X or an O on the game board.
1. The diagram below 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?
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.
2. 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.
3. 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.
4. Oxygen is a product of photosynthesis. The primary role of this oxygen in cellular respiration is to
A. yield energy in the form of ATP as it is passed down the respiratory chain.
B. act as an acceptor for electrons and hydrogen, forming water.
C. combine with carbon, forming CO2.
D. combine with lactate, forming pyruvate.
5. Which of these statements would be correct in relating carbon dioxide levels and photosynthetic rate?
A. As the CO2 level increases, photosynthetic rate increases.
B. As the CO2 level increases, photosynthetic rate decreases.
C. As the photosynthetic rate increases, the CO2 level increases.
D. As the photosynthetic rate increases, the CO2 level decreases.
6. 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.
7. 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, 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.
8. Photosynthesis is a part of various cycles that help to move oxygen and carbon through the environment. What form of abiotic (nonliving) carbon do
plants remove from the environment?
A. glucose
B. starch
C. carbon dioxide
D. ATP
9. Which of the following best represent the final prodcuts of the chemical reactions that take place inside the organelle labeled A
in the diagram?
A. sugars, oxygen
B. ATP, electrons
C. ATP, sugars
D. carbon dixoide, water
Station 4: Photosynthesis/Respiration Comparison LAB
Anaerobic/Aerobic Card Sort
Bromothymol blue is an indicator that changes from blue to yellow in the presence of carbon dioxide (CO 2).
In an experiment, four test tubes were filled with a mixture of
Bromothymol blue and water. The first test tube contains only the liquid.
An aquatic plant was added to the second test tube, and a snail to the
third one. The last test tube contains both an aquatic plant and a snail.
Station 4 continued: Cellular Respiration – Anaerobic/Aerobic

These four test tubes were placed in sunlight for 48 hours. Observe the
changes in color from the original set-up that had occurred.
