Plant Photosynthesis

Exercise 1: Carbon, Light, and Photosynthesis

Questions

A. What was the purpose of creating a sodium bicarbonate solution? What was the purpose of adding soap to the solution?

B. Why does a floating leaf indicate that photosynthesis is occurring?

C. Is it possible that photosynthesis is occurring in a leaf that is not floating? Explain this and support your answer with your data.

D. Would spinach leaves have a greater rate of photosynthesis in the bicarbonate solution you created or in atmospheric air? Support your answer.

E. Does the light-independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment?

F. Write a short discussion describing trends in the data: compare the control cups (distilled water) versus the experimental cups (bicarbonate solution) and compare the light versus dark environments.

G. Was your hypothesis supported or refuted? Write a one-to-two sentence conclusion to summarize your experimental findings.

Exercise 2: Investigating Photosynthesis

Questions

A. Report your data. Include any graphs or tables you have created in Data Table 5.

B. Write a short discussion that describes your experimental findings: describe in words the trends in the data that you recorded.

C. Was your hypothesis supported or refuted? Write a short one-to-two sentence conclusion that summarizes your findings.
