What does determine the direction of water movement into or out of the cells ?

Question

yeah .. that is pretty much my question . please REESPSOOND . (:

Answer 1

The concentration of water inside versus outside. If there is a greater concentration of water outside, the water will stay into/come into the cell. If the concentration of the water is greater inside, the water will try to escape to the outside. Think of it this way, if you put too much air inside a balloon it will grow and grow until it's too full and the air has to escape, and it's similiar with water in a cell, if the cell gets too full the water will want to escape out to where it's not as full.

Answer 2

If you want to be 100% accurate, the difference in the water potential in and out of the cell. Water will move from the region where it has higher potential to the region of lower potential.
The potential of water depends on the concentration of solutes but also pressure. Distilled water in a container open to the atmosphere has potential 0 MPa. Dissolving things in water tends to make the potential more negative.

Some people tend to overlook the pressure factor and focus only on the solute contribution (osmotic pressure). However be carefull not to forget about the pressure factor especially when dealing with plant cells where you have the building up of turgor pressure to stop the entry of too much water when you put the cell in a hypotonic solution.

Answer 3

Osmosis is the predominant factor for water movement in and out of cells because membranes are permeable to water. Actively pumping solute in and out of cell creates a balance along with controling solute levels just outside the cell

Answer 4

right it extremely is the way it extremely works: cellular in a hypotonic answer: If the concentration of salt interior the cellular is bigger than it is outdoors the cellular, then water will flow the cellular. cellular in a hypertonic answer: If the concentration of salt interior the cellular is below it is outdoors the cellular, then water will flow out of the cellular. cellular in an isotonic answer: If the concentration of salt is equivalent interior and out of doorways the cellular, then no water flows into or out of the cellular (surely). observe: i exploit salt right here, even though it is surely sodium (Na) and can be different molecules besides.

Answer 5

Without any energy expended it would normally flow toward the lower concentration whether in or out of the cell.

Answer 6

Concentration of solutes. You can kind of think of it as water having to "dilute" the concentration of solutes. Osmolarity.

Answer 7

the greater amount of water will always travel into the lesser amount of water:ie in or out- until the amounts are even

Answer 8

try typing osmosis and then diffusion into wikipedia

Answer 9

water moves to where there is less of it -diffusion
