Question
Using a straw to blow into the bromothymol blue solution eventually turns the solution a green color. What gas is being blown into the solution that causes it to turn green?
A. The absence of carbon dioxide
B. The presence of carbon dioxide
What color will the water be if photosynthesis has occurred?
Read the following description of Tube #4:
Tube #4 contains:
bromothymol blue(BTB)
carbon dioxide
not exposed to light
no elodea present
initially yellow-green in color
After 24 hours, Tube #4 is still yellow-green in color. Which of the answer choices below describes why?
A. Tube #4 is still yellow-green in color because it performed photosynthesis
B. Tube #4 is still yellow-green in color because the carbon dioxide was absorbed
C. Tube #4 is still yellow-green in color because carbon dioxide was released
D. Tube #4 is still yellow-green in color because it was unable to perform photosynthesis
Read the following description of Tube #2:
Tube #2 contains:
Bromothymol blue (BTB)
Carbon dioxide
Exposed to light

Initially yellow-green in color
After 24 hours, Tube #2 is now blue in color. in 1-2 sentences explain why.
During preparation, baking soda (NaHCO3) is added to the water to create a solution. Which of the options below is the best reason why baking soda was added?
A.TO ADD CARBON DIOXIDE TO THE SOLUTION THAT THE PLANT NEEDS AS A REACTANT OF PHOTOSYNTHESIS
B. To add oxygen to the solution that the plant needs as a reactant of photosynthesis
C. To keep the elodea plant from decaying
D. To keep the water from changing into another color
During the first portion of the experiment, the lights were turned off and a timer was set for 5 minutes. No bubbles were released during this 5 minutes. Which of the answer choices below is the best reason why.
A. There was no light present for photosynthesis to occur
B. There was no oxygen present for photosynthesis to occur
C. There was no carbon dioxide present for photosynthesis to occur
During the second part of the experiment you can see bubbles begin to appear when they didn't before. Which of the answer choices below is the best reason why?
A. Carbon dioxide
B. Oxygen was present in the water when it wasnt before
C. Light was applied to the scenario so photosynthesis could occur
