Lab Report 4 on Determination of the Rates and Optimal Temperature for Aerobic Respiration and Photosynthesis.

BIOL3221L Lab 4 Report Requirements Worth :10 % of Final Grade Submission Deadline :Your lab 4 report is due on Thursday, November 12 th at 11:59 PM.Lab reports will be submitted through the lab Nexus site in the Assignments folder. A late penalty of 5%/day will apply to reports received after the deadline. NO reports will be accepted after Thursday, November 19 th (one week late). Guidelines : Be certain to read the General Guidelines for Lab Reports, which can be found in the Lab Manual & Info folder on Nexus, in order to familiarize yourself with the expectations for your report. Failure to follow these guidelines will result in deductions. The number of marks and which will be assigned, as well as the word limits (if applicable), for each section are indicated below. The specific requirements for data inclusion are also provided. Again, ifyou are uncertain about any of the requirements for your report, please contact your instructor for clarification. Plagiarism or academic dishonesty in any form will not be tolerated. Be certain to familiarize yourself with the university regulations. Total Marks (100 marks) Title Page (0.5 marks) Abstract (7marks; 250 word max) Introduction (20 marks; 1000 word max ) Include an introductory paragraph. You must state your general hypothesis/purpose in the introductory paragraph. Explain, with references, the general theory behind cellular respiration and photosynthesis, focusing on the specific processes you are investigating. Explain why you are using the techniques you are using. Why is oxygen consumption/evol ution a useful means of monitoring these processes? Why is temperature important in these processes? Why are we monitoring pH? Provide sufficient information in this section for your reader to understand why you performed the experiments you did and how they work. Conclude your introduction with abrief summary of the methods you will employ and the purpose of your work. State your specific hypotheses to be tested in your concluding paragraph. Methods (10 marks; no word limit ) Results (30 marks; no word limit ) Please include the following results using the data posted on Nexus: -Table of rates of oxygen/min/mL with individual trials, average, & standard deviation for yeast respiration -Table of rates of oxygen/min/mL with individual trials, average, & standard deviation for Euglena respiration -Figure of average cellular respiration rates for yeast and Euglena .You should include error bars at each temperature. Use a curved line to connect the data points for each species -Table of rates of oxygen/min/mL with average, & standard deviation for observed and actual rates of photosynthesis. You will need to determine the actual rate for each trial before determining the average and standard deviation -Figure of average observed and actual photosynthesis rates. You should include error bars at each temperature. Again, use acurved connecting line. -Include a statement(s) in the text of your results which incorporates the observations provided to you for the addition of CCCP in the oxygen electrode experiments. -Graph of class data for pH over time. Include dark and CCCP conditions on the same graph, each with curved connecting lines. You do not need to include atable of values for this experiment. *Again you may choose to organize this data in anumber of ways, and may include more than one experiment in a single table. However, remember to include information in alogical sequence which provides for anarrative. Also, the figures/tables support the text, not the other way around! Discussion (30 marks; 1000 word max ) Remember to avoid simply reciting your results (already done) and instead to present your findings in the context of what they mean and how they relate to one another. You should also provide references to information which supports your observations and conclusions about the processes you are investigating. Address the validity of your experiments, and means of improving or extending them. Are there further hypotheses you could test? What is the overall significance of your findings? References (2.5 marks) You should include a minimum of 7 references (including the lab manual). Again, you may need to utilize websites to find appropriate information. Try to find reliable sources and be certain to reference appropriately.
