Question:
Complete the tables below using your data and information found under the Background tab (see the Summary of Needed Formulas section)
Leaf Sample Type | Illumination Level | Oxygen Concentration Change Data (ppm) | Elapsed Time (s) | Oxygen Change Rate (ppm/s) |
Sun- Adapted | 100% | 21.36 | 40/s | 0.534 |
Shade-Adapted | 100% | 12.96 | 40/s | 0.324 |
Leaf Sample Type | Illumination Level | Carbon Dioxide Concentration Change Data (ppm) | Elapsed Time (s) | Carbon Dioxide Change Rate (ppm/s) |
Sun- Adapted | 100% | -21.36 | 40/s | -0.534 |
Shade-Adapted | 100% | -12.96 | 40/s | -324 |
Observations and Questions
[1] Show your oxygen change rate calculation for the Sun-Adapted data run.
[2] Show your carbon dioxide change rate calculation for the Shade-Adapted data run.
[3] Examine your results. Do your results reveal a possible relationship between (rates of) production of oxygen and carbon dioxide? Explain. Cite your results as part of your explanation.
[4] Using your results for change in oxygen concentration as a reference, discuss whether your Procedure I results confirm research findings about differences in the amount of chlorophyll production for sun-adapted and shade-adapted leaves.
[5] How is the net photosynthesis rate related to the rates you determined? (note that this is not a calculation)
[6] Explain why (or why not) you would expect respiration to occur when the illumination is 100%?
