What is osmotic pressure and what stops the flow of water? is it the water or solute??

Question

I actually understand a bit of osmotic pressure, i just really want to know what stops it?

THANKS

Answer 1

basically water flows from high pressure to low pressure...so when the pressure are equal...( like the outside pressure of a cell and the inside pressure) then the net movement is zero. It is said to be isotonic

Answer 2

Osmotic pressure is the hydrostatic pressure produced by a solution in a space divided by a semipermeable membrane due to a differential in the concentrations of solute. The higher the concentration of the solute, the higher the pressure. Water flows from the low pressure side of the membrane to the high pressure side. When the osmotic pressure is equal on both sides, the flow of water will stop.

Answer 3

Osmotic pressure is the hydrostatic pressure produced by a solution in a space divided by a semipermeable membrane due to a differential in the concentrations of solute. Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.

Answer 4

Osmosis is the movement of water across a semipermeable membrane from an area of high concentration to low concentration.  Osmotic pressure builds when the concentration of solutes on one side of the membrane is higher than the other.  So the water flow only stops when the concentrations become equal or the cells burst.
