Lab 3: Purpose?
1. Describe the procedures we used to detect polysaccharides, simple sugars, proteins and lipids.
2. Recognize the significance of the color changes.
3. Compare the Biuret test results of albumin and pepsin, the Benedicts, and starch results for potatoes and onions, and describe how one can determine the relative amounts of sugars present in a sample using the Benedicts test.
4. Identify an unknown organic compound by interpreting data recorded for these tests.
5. Know some potential sources of error.
6. Explain the importance of controls.
Lab 4: Purpose?
1. Identify whether a cell is a likely a prokaryote or a eukaryote based on observations of that cell under a microscope. Identify all of the organisms that you viewed. Know all of the names, the test is not multiple choice! Know which formed multi-cellular structures and which did not.
2. Compare the how the pigments of Elodea, red pepper and purple onion skin are distributed in a cell.
3. Describe the appearance of chloroplasts in Elodea, what is streaming?
