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.
Does placing plant cells in a hypotonic solution causes the osmotic pressure to increase?
When a plant cell is placed in a hypotonic solution, the osmotic pressure tends to increase as the water in the cells moves to a place elevated in solute concentration. The osmotic pressure is the chief cause of support in numerous plants.
Do plant cells undergo meiosis?
No, plant cells do not undergo meiosis. Meiosis occurs in reproductive cells, such as pollen or ovule cells in plants, where it is responsible for producing genetically diverse haploid cells for sexual reproduction. Regular plant cells, such as those in roots or leaves, do not undergo meiosis.
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!!
What is a an osmoticum?
Any substance that acts to supplement osmotic pressure in a plant or a culture of plant cells. An agent, such as PEG, mannitol, glucose or sucrose, employed to maintain the osmotic potential of a nutrient medium equivalent to that of the cultured cells (isotonic). Because of this osmotic equilibrium, cells are not damaged in vitro.
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.

Plant cells are protected by their rigid cell walls, which provide structural support and help prevent cell lysis.
Placing plant cells in a hypotonic solution causes the osmotic pressure to?
Placing plant cells in a hypotonic solution causes osmotic pressure to increase as water enters the cells. This influx of water leads to turgor pressure, which helps maintain the structural integrity and rigidity of the plant cells. As the cells swell, they become turgid, supporting the overall stability of the plant. However, if the pressure exceeds the cell wall's capacity, it could lead to cell lysis.
Can animal cells undergo plasmolysis?
Animal cells undergo lysis, and plant cells undergo plasmolysis. Lysis occurs when a plant cell explodes due to too much pressure on the inside, and plasmolysis occurs when the vacuole of a plant cell shrinks away from the cell wall due to lack of water.
Which osmotic environment is best for plant cells?
A plant cell is best in a hypotonic environment
Can plant cells undergo osmosis?
no
Do plant cells have a larger vacuole than animal cells?
To maintain high osmotic potential
Why do plant cells undergo both photosynthesis and respiration?
because plant cells are organism that can live through life
Are chloroplast in animal cells?
no. Chloroplasts are only in plant cells. chloroplasts are what makes the plant green.

What process do plant cells undergo to provide oxygen for all living things?
everything in the plant
What will happen to cells if they are left in distelled water?
If cells are placed in distilled water, they will undergo osmosis, where water moves into the cells due to a lower concentration of solutes outside compared to inside the cells. This influx of water can cause the cells to swell and potentially burst, a process known as lysis, particularly in animal cells. Plant cells may become turgid, which is beneficial for maintaining structure, but excessive water can also lead to cell damage.
How does osmotic pressure affect plants structure?
Osmotic pressure is crucial for maintaining turgor pressure in plant cells, which is the pressure of the cell contents against the cell wall. When a plant's cells are fully hydrated, osmotic pressure helps keep them rigid and supports the overall structure of the plant, allowing it to stand upright. Conversely, if osmotic pressure decreases due to water loss or lack of solutes, cells can become flaccid, leading to wilting and reduced structural integrity. This balance is essential for growth, nutrient transport, and overall health in plants.
