Bacteria Structures Review Game

Front

What type of bacteria retains the crystal violet stain during Gram staining?

Back

Gram positive bacteria retain the crystal violet stain.

Front

What is the primary component of the bacterial cell wall that is targeted during Gram staining?

Back

Peptidoglycan is the primary component of the bacterial cell wall targeted during Gram staining.

Front

What is the function of flagella in bacteria?

Back

Flagella allow bacteria to move by propelling them through their environment.

Front

What color do gram negative bacteria appear after Gram staining?

Back

Gram negative bacteria appear pink or red after Gram staining.

Front

What is the first step in the Gram staining process?

Back

The first step in the Gram staining process is the application of crystal violet.

Front

What distinguishes gram positive bacteria from gram negative bacteria in terms of cell wall structure?

Back

Gram positive bacteria have a thick peptidoglycan layer, while gram negative bacteria have a thin peptidoglycan layer and an outer membrane.

Front

What is the role of the outer membrane in gram negative bacteria?

Back

The outer membrane in gram negative bacteria provides an additional barrier and can protect against certain antibiotics.

Front

What is the purpose of using a counterstain in Gram staining?

Back

The counterstain (usually safranin) is used to color gram negative bacteria, allowing them to be visualized after the crystal violet is washed out.

Front

What is the significance of Gram staining in microbiology?

Back

Gram staining is significant because it helps classify bacteria and informs treatment options based on their cell wall structure.

Front

What type of bacteria would you expect to be more resistant to antibiotics, gram positive or gram negative?

Back

Gram negative bacteria are generally more resistant to antibiotics due to their outer membrane.
