Bacteria are divided into two groups based on how their cell walls absorb?
Bacteria are divided into two groups based on how their cell walls absorb the Gram stain. Gram-positive bacteria retain the stain due to their thick peptidoglycan cell wall, while Gram-negative bacteria do not retain the stain because of their thin peptidoglycan cell wall and an outer membrane.
Do gram negative bacteria have peptidoglycan in their cell walls?
No, gram-negative bacteria do not have peptidoglycan in their cell walls.
Does Gram-positive bacteria have peptidoglycan in their cell walls?
Yes, Gram-positive bacteria have peptidoglycan in their cell walls.
Which part of bacteria cell is most involved in gram stain?
The cell wall of a bacterial cell is the most involved in the Gram stain because it determines whether the bacteria will appear purple (Gram-positive) or pink (Gram-negative) after staining. The composition of the cell wall, specifically the presence of peptidoglycan, influences how the stain interacts with the bacteria.
What cell parts take the stain in?
In Gram staining, the cell wall of bacteria takes the stain differently based on their structure. Gram-positive bacteria retain the crystal violet stain, appearing purple, because they have a thick layer of peptidoglycan in their cell wall. Gram-negative bacteria do not retain the stain well and appear red after the counterstain with safranin, as they have a thinner layer of peptidoglycan and an outer membrane.

Gram-positive bacteria have a thick cell wall composed of?
Gram positive bacteria are so called because their cell walls are one thick layer of peptidoglycan, basically, so the stain is trapped in the cell wall and not rinsed away.
Do gram negative bacteria have peptidoglycan in their cell walls?
No, gram-negative bacteria do not have peptidoglycan in their cell walls.
What is the difference between gram plus and?
Gram positive bacteria stain purple with the Gram stain. This is because of the fact that they contain a thick layer of murein in their cell wall, which takes up the stain very well. Gram negative bacteria, however, do not display the thick layer of peptidoglycan on their outer surface. Therefore, they stain red with the counter stain.
Does Gram-positive bacteria have peptidoglycan in their cell walls?
Yes, Gram-positive bacteria have peptidoglycan in their cell walls.
Why would bacteria stain gram variable?
A gram-negative cell will lose its outer membrane and the peptidoglycan layer is left exposed. or it is best to use younger cells ( 12-24hr) because older gram positive bacteria are subject to break down of the cell wall by enzymes that are produced with age which may result ingram variable staining.

What physical part of bacteria is responsible for the color difference at the end of the gram staining process?
In Gram positive bacteria it is the cell wall made up of a thick layer of peptidoglycan which holds the stain so that this bacteria can be viewed. Gram negative bacteria have two thin layers of peptidoglycan which loses the stain in the secondary washing, hence their terminology as negative.
Why are some bacteria gram-positive and some gram-negative?
During a gram stain some bacteria retains the stain because they are gram positive with thicker walls . If the bacteria does not stain either it is an endospore bacteria or gram negative with thinner walls, so colorless or red color.
If a cell has peptidoglycan but no nucleus what kingdom does it belong to?
If the cell contains peptidoglycan but contains no nucleus, the cell is a bacteria, and therefore belongs in either kingdom eubacteria or kingdom archaebacteria.
Which structure of bacteria is determied by gram staining?
The part of the bacterial cell that appears to play the most important role in determining whether an organism if gram-positive or not is the cell wall. it is determined by whether or not it retains the stain during testing.
