what microbial features would you use a scanning electron microscope and transmission electron microscope to observe.

What are the structural differences between Gram-positive and Gram-negative bacteria cell walls? Can you explain what would happen to the cell wall's physical integrity while applying the Gram staining technique?

You are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative. 9) What makes the bacteria Gram negative?10) Approximately how long would it take you to finish the entire procedure

For a laboratory exercise of basic techniques in microbiology: Gram stain and Microscopy. What is the answer of table

Why are bacterial cells generally stained for microscopic viewing?

If you were working with an unlabeled simple stained smear, would you be able to identify the bacterial species by observing the slide under the microscope? Why or why not?

You are interested in studying the surface structure of an Archaea cell, what type of microscopy will you use? a) scanning electron microscopy b) phase-contrast microscopy c) transmission electron microscopy d) bright-field microscopy

A colleague performs a smear prep from a colony on an agar plate. Without staining it, he looks at it under oil immersion with a light microscope (1000x magnification). “Hm," he says, "it's not purple, so it must be gram negative." Briefly explain the error in his logic, and say what he would have to do to show whether the organism is gram negative or gram positive. Your Answer:

An acid-fast stain can be used to detect protective coverings found in using light microscopy. organisms incorporating mycolic acid in the cell wall organisms forming endospores organisms with capsules organisms with Gram-negative cell walls

You use gram staining procedure to stain a bacterium that lacks a cell wall. What color will the bacterium be after staining procedure is finished?
