BIO 250L Lab 3 Structure & Microscopy: Questions With Correct Answers | Latest Update Graded A+

BIO 250L Lab 3 Structure & Microscopy: Questions With Correct Answers | Latest Update Graded A+. Table 1: Experiment 1 Staining Observations Stain Used: Crystal Violet. Observations: The organism's color changed to purple, and the shape observed was rod-shaped. Post-Lab Questions 1. How does crystal violet enhance the visualization of microbial features? Crystal violet improves microbe visualization by creating a contrast between the slide and the germs, making it easier to visualize and study these bacteria and other microbes.Furthermore, crystal violet penetrates the cell membrane and walls, dyeing the microbiological characteristics. 2. What are some of the limitations of simple staining? Simple staining has several limitations in that it can only determine and tell the shape and size of the cell wall but not the particular color.It's difficult to identify these structures only based on their shape and color. “Lab 3 Structure & Microscopy BIO250L” 3. Give an example of a situation in a lab or medical setting in which simple staining would be utilized. Simple staining is used to analyze various structures of the material as well as the contrast in their shape, size, and cell grouping of these bacteria, as well as their background. Simple staining can be accomplished with methylene blue or crystal violet. Insert a photo of your stain. Include your name and access code handwritten in the background of your photo.
