the sodium potassium pump uses ATP (energy) to move Na & K in and out of cells. Na is a cation that is found primarily in extracellular fluid and has a strong affinity for water. K is primarily inside of the cells. if there is a build up of intracellular fluid, Na can move out of the cell and bring some water with it, thus reducing the pressure inside of the cell. if a cell is dehydrated and needs fluid, Na can move into the cell and bring water with it, thus rehdyrating the cell. Both Na and K are involved in the electrical potential of cells also.
What else can I help you with?
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.
Are contractile vacuoles found in animal or plant cells?
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.
What is a structure that plant and fungus cells have that help keep from bursting?
Plant cells have a cell wall made of cellulose, while fungal cells have a cell wall made of chitin. These rigid walls provide structural support and help prevent the cells from bursting due to osmotic pressure.
Why can an animal cell change shape but a plant cell cannot?
Plant cells have rigid cell walls made of cellulose that provide structural support and prevent drastic changes in shape. Animal cells do not have a cell wall and rely on their cytoskeleton for support, allowing them to change shape more easily.
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.
How do organisms prevent cells from bursting?
Diffusion in and out of the cells depending on the surounding environment keeps the cells from bursting with excess fluid.
Why do animal cells easily rupture and burst but plant cells rarely do?
Plant cells have a cell wall, which is important for support and to maintain rigidity. If the plant cell swells with water, the cell wall stops it from bursting. Animal cells do not have cell walls, and so they are not protected from bursting.
Why cell lysis occurs for animal cell not for plant cell?

They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.
Why plant cells in distilled water do not behave exactly same way as animal cell?
Animal cells will burst because they have no outer structure to allow them to keep their shape. However, plant cells have a cell wall which keeps the cell from bursting.
What is a structure that plant and fungus cells have that help keep from bursting?
Plant cells have a cell wall made of cellulose, while fungal cells have a cell wall made of chitin. These rigid walls provide structural support and help prevent the cells from bursting due to osmotic pressure.
What organelle keeps some animal cells from bursting in a hypotonic solution?
The contractile vacuole in some animal cells helps regulate osmotic pressure by actively pumping out excess water that enters the cell in a hypotonic solution. This prevents the cell from bursting due to the influx of water.
Why can an animal cell change shape but a plant cell cannot?
Plant cells have rigid cell walls made of cellulose that provide structural support and prevent drastic changes in shape. Animal cells do not have a cell wall and rely on their cytoskeleton for support, allowing them to change shape more easily.
What is bursting of cells called?
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 cell structure do animal cells lack that prevent them from preforming the process of photosynthesis?
Animal cells lack chloroplasts and as such cannot photosynthesise.
What structure do plant cells have that animal cells do not keeps them from bursting in a hypotonic solution?
Plant cells have a rigid cell wall made of cellulose that provides structural support and prevents bursting in a hypotonic solution. Animal cells do not have a cell wall, which makes them more susceptible to bursting in a hypotonic environment.
