Direction: Read and analyze the following laboratory experiment and answer the following question. PART 3: PLASMOLYSIS Materials: safety goggles, red onion, dropper, slides & cover slips, tweezers/ forceps, compound microscope, iodine, small knife, water, salt (5% and 10% solution) Methodology: 1. With goggles on, carefully cut the onion into wedge shaped pieces using a knife. 2. Use an eye dropper to place a drop of water in the center of a microscope slide. Use the tweezers to peel a thin layer of skin tissue from the thick part of the onion wedge and place it in the center of the microscope slide. 3. 4. 5. Add a drop of water and a drop of iodine over the onion tissue on the slide. Carefully lower a cover glass slip at an angle on the stained tissue to allow air bubbles to escape. 6. Examine the prepared slide under the compound microscope at 100X magnification. 7. Record what the cells look like. 8.

4. TLC is still useful in the lab but is being replaced by automated chromatographic methods. For example, TLC, FPLC, and HPLC are now automated processes, and computers can control various parameters, such as flow rate, blends of solvent mixtures, etc. Can you think of how the ability to manipulate the parameters of these automated chromatographic methods (sample size, column plate length, flow rate, solvent gradients, etc.) might accentuate or improve an investigator's ability to separate amino acids or other biomolecules?
