Let's break down the questions and provide the best responses:
Question 3: Which colors (wavelengths) of light show increased "action" of oxygen production through redox processes?
- Response: Blue and red light
These wavelengths are typically associated with higher rates of photosynthesis because chlorophyll, the pigment used by plants, absorbs blue and red light most effectively.
Question 4: Using the production of oxygen from redox reactions in photosynthesis as a measure, why did the experimenter most likely choose aerobic bacteria to show him which colors (wavelengths) of light are most productive?
- Response: Aerobic bacteria grow and reproduce where there is the most abundant source of oxygen.
Aerobic bacteria require oxygen to survive and thrive, so they would be found where oxygen production from photosynthesis is highest, allowing the experimenter to measure productivity based on bacterial growth.
Question 5: Which statement best supports the correlation between frames b and c giving the experimenter the data that revealed which colors (wavelengths) of light best catalyze redox reactions in plant photosynthesis?
- Response: Aerobic bacteria congregated (gathered) along the alga where the most oxygen was produced connecting the action spectrum to the growth of bacteria AND the rate of redox.
This response emphasizes the relationship between oxygen production and the presence of aerobic bacteria, which is critical for understanding the effectiveness of different light wavelengths in driving photosynthesis.
