Does a bacteria cell have a cell membrane?
Some have outer membrane, some don't. Gram positive bacteria - no outer membrane Gram negative bacteria - with outer membrane
Are archaebacteria gram positive or gram negative?
Archaebacteria are neither gram positive nor gram negative because they do not have peptidoglycan in their cell walls like bacteria. Instead, they have unique cell wall structures that make them distinct from both gram positive and gram negative bacteria.
What is the difference between cell wall of gram positive and gram negative bacteria.?
Gram positive bacteria cell walls have a thick layer of Peptidoglycan and no periplasmic space. Gram negative bacteria cell walls have inner and outter cytoplasmic membranes with a periplasmic space in between. these also have a thin layer of Peptidoglycan. The outter cytoplasmic membrane of gram negative bacteria contains lipopolysaccharides.
Why does some bacteria stain purple and some red?
The purple stained bacteria are called gram positive bacteria and retain the stain after washing by having a thick cell wall one one layer of a heavily crossed linked material called peptidoglycan. ( Google that ) The red stained bacteria are gram negative because they posses two thinner layers of peptidogylcan cell wall that that do not hold the gram stain and it is mostly washed away in rinsing the bacterial samples.
How does the cell wall aid in classifying bacteria?
The presence or absence of a cell wall is a key characteristic used in classifying bacteria. Bacteria are classified into two major groups based on their cell wall structure: Gram-positive bacteria have a thick peptidoglycan layer in their cell wall, while Gram-negative bacteria have a thinner peptidoglycan layer surrounded by an outer membrane. This classification helps scientists differentiate between different types of bacteria.
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 type of coating on a bacteria cell?
In bacteria, the cell wall is composed of peptidoglycan, and is essential to the survival of many bacteria. Bacteria have been classified into Gram-positive and Gram-negative based on the structure of the cell wall. Gram-positive bacteria possess thick cell wall consisting of many layers of peptidoglycan and teichoic acids. Gram-negative bacteria have relatively thin cell wall consisting of few layers of peptidoglycan.
Do gram negative bacteria possess two cell membranes?
Yes, gram-negative bacteria have two cell membranes: an inner membrane and an outer membrane.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
What is the difference between the gram-positive bacteria and gram-negative bacteria?
They have different cell walls.
Does a bacteria cell have a cell membrane?
Some have outer membrane, some don't. Gram positive bacteria - no outer membrane Gram negative bacteria - with outer membrane
What type of bacteria has an lipopolysaccharide layer outside the peptidoglycan layer?
Gram-negative bacteria have a lipopolysaccharide layer (LPS) outside the peptidoglycan layer in their cell wall. The LPS layer serves as an endotoxin and is an essential component of the gram-negative cell envelope.
Do bacteria have many cells?
the bacteria cell has only one cell and they are called unicellular.they reproduce with asexual reproduction. the bacteria are called different archaebacteria.
What is the outer most border in a bacteria cell called?
The outermost border in a bacteria cell is called membrane. This is also commonly referred to as the cell wall.
Name the different gram positive and gram negative bacteria?
