What will happen if a bacterial cell is placed in distilled water with lysozyme?
The bacterial cell will undergo osmotic lysis due to the hypotonic environment created by the distilled water, causing water to enter the cell and potentially burst it. The presence of lysozyme will further damage the bacterial cell by breaking down its cell wall, making it more susceptible to lysis.
Why cell lysis occurs for animal cell not for plant cell?
Cell lysis occurs more easily in animal cells than in plant cells because animal cells lack a rigid cell wall like plant cells do. The absence of a cell wall in animal cells makes them more susceptible to bursting under osmotic pressure changes or when exposed to external stressors. Plant cells are protected by their rigid cell walls, which provide structural support and help prevent cell lysis.
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 happens to a cell that has its peptidoglycan disrupted or removed?
It would rupture from internal pressure,with this cell wall incomplete or missing such cells have very little protection from lysis. Lysozyme an enzyme contained in tears in saliva, provides a natural defense against certain bacteria by hydrolyzing the bonds in glycan chains and causing the wall to break down.

What is it called when a animal cell swells and bursts when entering water?
The process is called osmotic lysis. This occurs when a cell takes in too much water due to a hypotonic environment, causing it to swell and eventually burst.
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
If gram positive bacteria are incubated with penicillin in an isotonic solution will it able to grow or lysed explain why?
The gram positive bacteria will be lysed when incubated with penicillin in an isotonic solution. Penicillin inhibits peptidoglycan synthesis, weakening the bacterial cell wall. The isotonic solution prevents osmotic lysis by maintaining equal concentrations of solutes inside and outside the bacterial cell, making the weakened cell wall more susceptible to lysis.
What is the protection from osmotic lysis?
Cells can protect themselves from osmotic lysis by regulating their internal osmolarity through mechanisms like pumping ions in or out of the cell to maintain a balanced osmotic pressure with the external environment. The cell membrane plays a crucial role in protecting against osmotic lysis by selectively allowing certain molecules to pass through while blocking others. Additionally, some cells have cell walls that provide structural support and prevent them from bursting due to changes in osmotic pressure.

What is the scientific name for when cells swell and burst?
The scientific term for when cells swell and burst is "lysis". This can occur due to factors such as osmotic imbalance or physical damage to the cell membrane.
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 mode of action of cepdoxime?
Cefpodoxime is a broad-spectrum cephalosporin antibiotic that works by inhibiting bacterial cell wall synthesis. It achieves this by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, disrupting the cross-linking of peptidoglycan layers. This leads to cell lysis and ultimately the death of susceptible bacteria. Cefpodoxime is particularly effective against various Gram-positive and Gram-negative bacteria.

Why does the nattharick's solution not do the lysis of white blood cells?
The Nattharick's solution does not cause lysis of white blood cells because it is an isotonic solution, meaning it has the same osmotic pressure as the cells. This balance in osmotic pressure prevents the solution from causing the white blood cells to take up too much water or lose too much water, which would result in cell lysis.
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.
