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%?
