1) Identify the research question:

2) Identify the hypothesis of the study:

3) Identify the study organism/organism of interest:

4) Identify the independent variable:

Hint: for the short-term experiments two different stem types were used, what was different between the two?
5)Identify one of the dependent variables:

Hint: a number of different sub-experiments were performed with the goal of answering the research question and addressing the hypothesis. Choose one and identify what was measured (the dependent variable).
6) Review the section about Plant Material in the Materials and Methods section. Identify two controlled variables:

7) The positive, negative, control and experimental groups are more difficult to identify in this research study. However, we can see that P-values were used to determine statistical significance between treatments. Examine the bar graph provided for Figure 6 parts A and B. Note that bars with overlapping error bars are labeled with the letter "a" while the bars that do not overlap are labeled "b". What do you think the "a" and "b" are trying to tell you?

8) What is the conclusion of the researchers regarding whether or not anthocyanins play a protective role against high light damage in plants?

9) Do you believe that the researchers were able to validate or invalidate their hypothesis? Why or why not?

10) Do you believe that the researchers were able to answer the question of the study? Why or why not?
