SAVE YOUR WORK. When you have completed this assessment, submit it to the appropriate Assignments area in Blackboard. Using the VUMIE Lab Manual, the VUMIE Lab website, your notes, and in some cases outside research, answer the following questions. Your answers must be in the form of complete and grammatically correct sentences. Highlight your responses or use a different font color (to distinguish them from the questions themselves). These questions are pulled (in order) directly from your lab manual. 10 points Bacterial Anatomy Morphology, and Arrangement Bacterial Anatomy 1: 1) Highlight or underline the correct answer(s) in each instance below, to describe the unknown organism found in the Gram stain. Gram reaction: Gram + Gram – Morphology: coccus bacillus spirillum other Arrangement: singles pairs chains clusters other 2) What is the terminology used for the cell anatomy and arrangement observed for this organisms . The terminology used for the cell anatomy and arrangement observed for this organisms is cocci 3) When you do a Gram stain, you use these four chemicals. Below, indicate the color of cells in a smear of this organism after use of the listed chemical during completion of a Gram stain. RE: Bacterial Anatomy 1 Unknown Organisms Crystal Violet Gram’s Iodine Decolorizer Safranin Bacterial Anatomy 1 unknown Organism purple Dark purple Light purple purple 4) When bacteria are stained, it is because the stain ions react with cell structures that have the opposite ionic charge (+ and – are attracted to one another). Use outside resources to find out this information: What cell structure(s) is (are) stained by the dye to give this organism the color observed? 5) The difference in color between Gram + and Gram – cells is due to structural differences. Use your text or other resources to answer this question. Indicate which of the following cellular features would be found in an organism exhibiting this Gram reaction. Highlight or underline the correct response(s) below. A. LPS layer present D. flagella with only two rings in basal body B. peptidoglycan present E. endotoxin present C. teichoic acids present F. periplasmic space present 6) Predict the cell wall structure of the unknown, based on the discussion of Gram + and Gram – cell walls found in your textbook. Bacterial Anatomy 2: 7) Highlight or underline the correct answer(s) in each instance below, to describe the unknown organism found in the Gram stain.
