Background information about the lab. Summarize the slides and the ‘introduction’ section in the lab manual (role of GA and ABA in germination, why potassium iodide was used (stops the reaction, interacts with starch to form a purple/blue color to measure absorbance), the relationship between starch, α-amylase activity, and absorbance). At least two citations should be included.
In the last paragraph, you should include: (i) state the purpose of the experiment, (ii) a brief overview of the experiment, (iii) a proposed hypothesis, and (iv) describe how an unknown concentration of GA will be found in a sample.
Equipment and material used (spectrophotometer, test tubes, reagents, timer).
Describe the treatments (tubes 1-4 were negative controls, 5-9 were treated with varied concentrations of GA, 10-14 were treated with varied concentrations of GA plus ABA, 15 was the unknown).
Describe the procedure that you followed (what you did in the lab).
