Conclusion
Discussion section
The Discussion section will discuss the results in context of broader meanings and in context of information from literature sources. Expected length is about 2 full pages. Your discussion should include the following sections and cover the following topics:
Conclusion: Assuming that the hypothesis of the exercise was that “All leaves contain photosynthetic pigments,” do your results support the hypothesis?
The “Explanation of Results” section you should discuss:
• What are the functions of chlorophyll, carotenoid, and anthocyanin type pigments? Cite and reference literature source(s) for this information.
• Which spots correspond to which types of pigments? Cite in “(author(s), year, pg #)” format and reference literature source(s) that supports this interpretation.
• Which leaves appeared to be capable of carrying on photosynthesis, or not? What is the evidence for this? If the tissue is not photosynthetic, what other function may it be serving? Cite and reference a literature source that supports these interpretations.
• Why might leaves of different plants have different amounts of pigments; how might this relate to their growth environment or other evolutionary adaptations? (Cite source information.)
