Coursework - Seed Protein Practical Report Instructions
You must submit this practical write-up ONLINE including both (1) an Excel workbook (the data analysis) and (2) a word document (the write-up) through the 'Life on Earth' Blackboard site.
1. An excel workbook; showing the cohort's results and data analysis.
The cohort's data will be provided as an excel workbook on Blackboard under the assignments tab for you to use for this assignment. You are required to read the instructions within this excel workbook, fill in the table and create two bar charts (within the excel workbook itself). You must then submit this excel workbook as part of your online submission.
2. The practical report; not exceeding 1000 words. To include:
• The Aims of the experiment (we suggest up to 100 words)
• A note of any changes to the experimental procedure given in the schedule (do not include a full methods section as this is not required).
• A written description of your Results (we suggest about 200 words). In this section you should describe YOUR result for the protein concentration of your chosen seed type (in comparison to the full data set for that species), as well as including a written description of the overall class results.
• A Discussion (we suggest about 700 words). This should be a critical appraisal of YOUR result and the class results in the context of information from the practical schedule. the textbooks and suggested websites. It should provide answer(s) to the questions at the end of the practical handout. but you don't have to formally answer them as listed - they are prompts to get you to think about the experiment.
• In a practical report use the PAST tense, i.e. "it was found".
• Write impersonally, i.e. "recordings were made" not "we made recordings".
• Type scientific names in italics e.g Daucus carota, (or underline e.g Vicia faba). N.B. for binomial names, the genus begins with a capital letter, the species does not.
• Don't forget to include the appropriate units (e g. cm-3, min, kg)
• Tables and Figures must have adequate captions that enable you to understand the graph on its own without reference to text elsewhere, i.e. not just a short title: units must be stated in the heading of each column in a Table or on the axes of graphs
• Use diagrams where appropriate.
Practical Seed Protein Analysis
Aim: To help you understand how and why plant seeds are used for protein production
Why? Because of the importance of amino acid production in plants to the living world and its implications for animal nutrition
Questions (to be answered as part of your discussion):
1. Comment on the results. Did the class results show a difference in protein content between legumes and cereals?
2. Why might legumes have more protein in their seeds?
3. Do your data accord with those in the table supplied?
4. What sources of error are there in this experiment?
5. Why are so many staple diets combinations of cereals and legumes?
6. Why do we have an essential requirement for certain amino acids but plants do not?
