- Gram-negative bacteria are generally more resistant to antibiotics than Gram-positive bacteria. What structure in Gram-negative bacteria (but not Gram-positive bacteria) is the basis of this difference?Identify the cell structure providing for cell morphology in the Staphylococcus epidermidis and Escherichia coli that you stained and examined. What unique macromolecule is found in this structure in both of them? How does that part of the bacteria differ between the two species?Using an appropriate lens and oil immersion, what would be a microscope's maximum resolution (in micrometres) that could use a wavelength of 350 nm (assuming that such a device exists)? What would be the surface-to-volume ratio for the coccus-shaped bacterium twice the size of the maximum resolution you calculated? Why is the surface-to-volume ratio an important biological factor. Explain. Show all of your calculations.
- Gram negative bacteria posseses a lipopolysaccharide (LPS) layer. how does this structural feature interact with human immune system?Both H+ and Ca2+ are ions that move through thecytosol. Why is the movement of H+ ions so much fasterthan that of Ca2+ ions? How do you suppose the speed ofthese two ions would be affected by freezing the solution?Would you expect them to move faster or slower? Explainyour answer.a. What can you observe in viewing your stained bacterial slide under the microscope if you fixed a lot of bacterial colonies in your slide during smear preparation? b. What can you observe in viewing your stained bacterial slide under the microscope if you heat fixed your slide in a much longer exposure to heat?
