The experiment utilized three chambers to investigate the impact of light on CO2 uptake by pea
plants. One chamber was completely covered
in aluminum foil. What is the MAIN purpose of
including this
chamber in the experiment?
a) To provide a baseline CO2 concentration for comparison.
b) To simulate the natural light cycle that plants experience.
c) To test the
effect of increased temperature on plant respiration.
d) To eliminate the influence of light on the pea plant altogether.
