Lab 3 Structure & Microscopy BIO250L Student Name: Access Code (located on the underside of the lid of your lab kit): Pre-Lab Questions 1. What determinesif a bacterial cell is Gram-positive or Gram-negative? The structure of a cell wall determines whether the cell is Gram-positive or Gramnegative The cell walls of Gram-positive bacteria are made up of thick layers of peptidoglycan. When Gram positive cells are treated to a Gram stain technique, they turn purple. Gram negative bacteria ha...

Student Name: Access Code (located on the underside of the lid of your lab kit): Pre-Lab Questions 1. What determines if a bacterial cell is Gram-positive or Gram-negative? Gram-negative bacterium have both a thin and an outer membrane layer, in contrast to Gram-positive bacteria, which have a dense peptidoglycan layer but no outside membrane. 2. In this lab, both viruses and prions were introduced as acellular organisms. Do some research and describe one other type of acellular organism...

1. Proper aseptic technique is crucial to ensuring growth of pure bacterial colonies. What is one experimental way you can test your practices to confirm that you are using proper aseptic technique?This could be done by having a control agar plate where sterile loop was used to streak the agar. If it grows bacterial colonies after some time, then aseptic technique was not successful. 2. In a laboratory setting, what are three ways you can properly sterilize culturing equipment? a. Dry hea...
