Are eukayotic cells from you gumline gram-positive or gram-negative?
Eukaryotic cells, such as those found in the gumline, do not fall under the categories of gram-positive or gram-negative bacteria. The gram staining technique is used to determine the cell wall structure of bacteria, not eukaryotic cells. Eukaryotic cells have a different cellular structure, including a nucleus and membrane-bound organelles.
Construct a Venn diagram to illustrate the similarities and differences between gram positive gram negative cells?
Not really possible to make a venn diagram, but here's a list: Similarities: In Bacteria Involve a peptidoglycan layer Differences Gram-negative is much more toxic Gram-negative is crystal violet in the Gram stain while Gram-positive is red
Is gram positive bigger than gram negative?
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
List the steps of the gram-staining procedure in order and fill in the color of gram-positive cells and gram-negtive cells after each step?

Can you gram stain a cell without a cell wall?
No, Gram staining primarily distinguishes bacteria based on their cell wall composition (Gram-positive vs Gram-negative). Cells without a cell wall, such as animal cells, cannot be Gram stained due to the absence of the target structure for the stain to bind to.
What colors gram positive and gram negative bacteria?
Gram-positive cells are purple and the Gram-negative cells are red.
Why will gram positive cells stain gram negative?
Contamination

Which step in the gram stain is the critical step in differentiating gram positive cells from gram negative cells?
Alcohol-acetone
Is shigella flexneri gram positive or negative?
When a gram stain is done on Shigella flexneri, the cells are light pink. This means that they are gram negative.

Are human cells gram positive?
Human cells are Gram-negative because they do not contain certain structures. More simply, if they don't have a cell wall they cannot be Gram-positive.
Does streptomycin kill gram negative bacteria?
Yes, streptomycin is effective against both gram positive and gram negative bacteria. It works by inhibiting protein synthesis in bacterial cells, leading to their death.
Can prokaryotic cells be either gram positive or gram negative?
Yes, prokaryotic cells can be either gram positive or gram negative. This is determined by the structure of their cell walls and how they react to the Gram staining technique. Gram-positive bacteria have a thick layer of peptidoglycan in their cell walls, while gram-negative bacteria have a thinner peptidoglycan layer surrounded by an outer membrane.
Is cholera gram negative or gram positive?
gram negative
