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.
