- True or False: both gram-positive and gram-negative bacteria have a cell membrane inside of their cell wall. True Falsearrow_forwardBacteria are microscopic single-celled organisms that are far too small to detect with the naked eye. Describe how you could grow enough bacteria in a colony to be viewed without a microscope. What is the relationship between the cells that form a colony?arrow_forwardImagine you are working in a microbiology lab. You perform an experiment where you take a culture of bacterial cells, transfer them to a new solution (Solution A), and then determine the number of living cells. You are surprised by the result: there are no living cells! Which of the following is a possible explanation for your observation? Solution A is hypertonic for your bacterium, resulting in the diffusion of water out of the cells. Solution A is isotonic for your bacterium, resulting in the diffusion of water out of the cells. Solution A is hypotonic for your bacterium, resulting in the diffusion of water out of the cells. Solution A is hypertonic for your bacterium, resulting in the diffusion of ions out of the cells.arrow_forward

Jim tells you that he predicts that gram positive bacteria, gram negative bacteria and archaeal cells will be equally sensitive to this antibiotic. Do you agree with Jim’s prediction? If you agree, explain in your own words why you agree. If you disagree, explain in your own words what you would predict and why.arrow_forwardWhat type of cell is circled in black?

- A student has a compound microscope equipped with 10X ocular lenses and 4X, 10X, 40X and 100X objective lenses. The student has a slide with cells that are -100 microns (1 micron = 103 mm) in diameter, and wants to view a magnified image of a %3D cell so that the cell appears to be 10 mm in diameter. Which objective lens should the student use? O 10X O 40X O 100X O 4X Question 7 2 ptsarrow_forwardPart B: Observation of Prokaryotic Cells Because of the small size of prokaryotic cells, your observation will focus on distinguishing between cell shape and cell arrangement. Together, appearance and arrangement are used to characterize bacteria. Bacteria have three basic shapes (Figure 7.1): cocci (spherical), bacilli (rod), spirilla (spiral). Bacteria can also be differentiated based on their cell arrangement (Figure 7.1): diplo (pairs), strepto (chains), staphylo (clusters).
