The cell wall prevents the cell from bursting because of a hypotonic environment, meaning that there is a high concentration of water moving into the cell that may have a lower concentration of water, by diffusion. When this happens, the cell may burst resulting in the destruction of the cell. the cell wall has interwoven fibers, preventing 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.
Why dont plant cells undergo osmotic lysis?
Plant cells have rigid cell walls made of cellulose that help maintain their shape and prevent them from bursting due to osmotic pressure. The cell wall provides structural support and prevents excessive water uptake, ensuring that plant cells do not undergo osmotic lysis.
What is the difference between lysis and plasmolysis?
When a cell is placed in a hypotonic solution, water will enter the cell. This is called lysis. When a cell is placed in a hypertonic solution, water will leave the cell (causing it to shrink). This is called plasmolysis.
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.
What are the ingredients in the lysis solution used for cell lysis?
The ingredients in the lysis solution used for cell lysis typically include detergents, salts, and enzymes. These components work together to break down the cell membrane and release the cellular contents for further analysis.

What makes bacterium burst?
Bacteria can burst, or undergo lysis, primarily due to the buildup of internal pressure caused by osmotic shock. When a bacterium is placed in a hypotonic environment, water enters the cell, increasing pressure on the cell wall. If the pressure exceeds the structural integrity of the cell wall, it can rupture. Additionally, certain enzymes, like lysozyme, can degrade the cell wall, leading to lysis.

What is the method of action for carbenicillin?
Carbenicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by interfering with the enzymes responsible for cross-linking peptidoglycan chains in the cell wall. This leads to cell wall weakening and eventual lysis of the bacteria.
What results from water pushing on the cell mambrane out to the cell wall in a plant cell?
A turgid condition that allows vascular plants to rise high enough to get leaves into good sunlit conditions. Lysis of the cell by hypotonicity is also avoided by having a cell wall in plants.

How do penicillins kill bacteria and what is the mechanism behind their antibacterial action?
Penicillins kill bacteria by disrupting the cell wall synthesis process. They work by inhibiting the enzyme transpeptidase, which is responsible for cross-linking the peptidoglycan chains in the bacterial cell wall. This weakens the cell wall, leading to cell lysis and ultimately bacterial death.
If the ribosome of a cell wall were destroyed what effect would this most likely have on a cell wall?
If the ribosome of a cell were destroyed, it would likely inhibit the cell's ability to synthesize proteins, including those necessary for building and maintaining the cell wall. Without these proteins, the structural integrity and functionality of the cell wall could be compromised, leading to potential cell lysis or instability. Consequently, the overall health and survival of the cell would be significantly affected.
Is the cell wall located outside the plasma membrane in bacterial anatomy?
Yes, in bacterial anatomy, the cell wall is located outside the plasma membrane. It provides structural support and protection to the cell, helping to maintain its shape and prevent lysis in hypotonic environments. The composition of the cell wall varies between different types of bacteria, with Gram-positive bacteria having a thick peptidoglycan layer, while Gram-negative bacteria have a thinner layer and an outer membrane.
