Why is gram negative bacteria less susceptible to osmotic lysis?

Because penicillin disrupts and destroys the peptidoglycan layer. Gram Negative bacteria have an outer membrane that blocks penicillin from getting to is peptidoglycan. Gram positive bacteria do not have this outer membrane, its peptidoglycan layer is out and exposed!!

Bdellovibrio is parasitic on gram-negative bacteria?
Bdellovibrio is predatory deltaprotobacteria , This bacterium predates gram-negative bacteria and lysis them (growing inside of them) forming clearing are on their lawnsBdellovibrio can only attack gram negative bacteria , however it attaches to both gram-nigative and positiveThe reason of that isn't known clearly yet !
What is cytolasm?
Actually called cytolysis, versus cytolsus, is also referred to as osmotic lysis. When a cell bursts, caused by an osmotic imbalance, it causes addition water to enter the cell and is called cytolysis.
What is complement how does it cause bacterial lysis what are some othere roles of complement?
Complement is a collection of proteins found in the blood that are effective against a wide variety of bacteria. Complement can cause bacterial lysis when the C5-C9 proteins are activated by C3. The C9 proteins insert into the bacterial cell membrane causing lysis and destruction of the bacteria.
What is it called when animal cells burst?
When animal cells burst it's called lysis.
Does eukaryotic cells contain a peptidoglycan cell wall?
Peptidoglycan is composed of amino acids and sugars that form the cell wall of a bacteria. Some of the properties of the cell wall include proving shape to the bacteria, preventing osmotic lysis, offer rigidity to the organism
The structure that surrounds the bacteria and gives it shape is known as?
This structure is called as Cell Wall that gives shape to the bacteria. This wall gives protection to the bacteria and prevents it from exploding because of osmotic lysis.
What is it called when cells burst because of osmotic pressure?
Cytolysis or Osmotic-lysis

What is lysis?
There are two meanings of Lysis In Biochemistry Lysis is the dissolution of cells,such as blood cells or bacteria as by the action of a specific Lysin that disrupts the cells membrane. In Medical terms Lysis is the gradual subsiding of the symptoms of an acute disease.

What is the role of sucrose in RBC lysis buffer?
The role of sucrose in lysis buffer is for subcellular fractionation. It refers to a laboratory technique that uses differential centrifugation to separate the different components of the cell.
What does low osmotic fragility means?
Osmotic fragility usually (unless otherwise mentioned) refers to the ease with which Red Blood Cells (RBCs) undergo lysis in a hypotonic solution. Before knowing what 'low osmotic fragility' means, one should know the concept of osmotic fragility. Different parameters, some of them related to the RBC and some of the extracellular environment have an effect on osmotic fragility. Low osmotic fragility means that the RBCs have a resistance against undergoing lysis when suspended in solutions which are hypotonic. They undergo lysis only if the solution is extremely hypotonic. In contrast, high osmotic fragility refers to the tendency of the RBCs to lyse even if the solution in which they are suspended in is mildly hypotonic. As an example for low osmotic fragility would be thalassemia. And as an example for high osmotic fragility, spherocytosis (a hereditary condition where the RBCs lose their usual biconcave structure and become spherical) causes increased osmotic fragility. i.e, It very easily lyses even at solutions which are mildly hypotonic... p.s Another interesting point to note is that in sickle cell anemia, the RBCs show increased mechanical fragility but decreased osmotic fragility. Elucidated by the fact that post-splenectomy the RBC lifespan increases.
What happens to a cell when it lyses?
Lysis, meaning to unbind, refers to the breaking down of a cell. This often happens by viral, enzymic, or osmotic mechanisms that compromise its integrity.
What is complement how does it cause bacterial lysis what are some othere roles of complement?
Complement is a collection of proteins found in the blood that are effective against a wide variety of bacteria. Complement can cause bacterial lysis when the C5-C9 proteins are activated by C3. The C9 proteins insert into the bacterial cell membrane causing lysis and destruction of the bacteria.
What is it called when animal cells burst?
When animal cells burst it's called lysis.
Why to use soft agar in phage titration?
Phage can move easily in soft agar,it can bind with another bacteria after lysis
Are mycoplasmas subject to lysis in hypotonic conditions?
Yes because mycoplasmas are the only bacteria known to lack cell walls
