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 have peptidoglycan in their cell walls?
No, gram-negative bacteria do not have peptidoglycan in their cell walls.
A cells boundary is called the what?
In animal cells, the plasma membrane forms the outer boundary of the cell. In fungi and plant cells, a cell wall exists outside the plasma membrane. Gram-positive bacteria have outer cell walls, while Gram-negative bacteria possess inner and outer plasma membranes.
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.
Why do mitochondria possess two membranes?
Mitochondria possess two membranes because they are believed to have evolved from a symbiotic relationship between a primitive eukaryotic cell and a prokaryotic cell. The outer membrane helps protect the organelle, while the inner membrane is where important processes like cellular respiration occur.
Which of the following possess glycerol-based phospholipids as part of their cell membranes?
Eukaryotic cells possess glycerol-based phospholipids in their cell membranes. Prokaryotic cells, such as bacteria, also have similar glycerol-based phospholipids in their cell membranes.
Do all cells have cell membranes?
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
Do bacteria have cell membranes?
Yes, bacteria does indeed have a cell membrane.
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 cell membranes found in bacteria cell?
Yes, every cell has a cell membrane.
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 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.
What processes can be found in both bacteria and protists?
Both bacteria and protists share processes such as reproduction, metabolism, growth, and response to stimuli. Additionally, they both possess genetic material in the form of DNA and have cell membranes that regulate the flow of substances in and out of the cell.
A cells boundary is called the what?
In animal cells, the plasma membrane forms the outer boundary of the cell. In fungi and plant cells, a cell wall exists outside the plasma membrane. Gram-positive bacteria have outer cell walls, while Gram-negative bacteria possess inner and outer plasma membranes.
What is the gooey slime that bacteria and cells have outside of their membranes?
cell wall
What does the cell membranes do in all the cells?
Protect the cell form any disease or harmful bacteria.
