In such a situation there is no net flow of water towards inside or outside of the cell.The flow of water is only possible in case of the placement of the cell in a hypotonic or hypertonic solutions.
Yes, water molecules will move in an isotonic solution, however - there will be no net movement. This means that the movement of water molecules in one direction will be cancelled out by a movement in the other direction.
No, it doesn't because the amount of solute within the plasma membrane and outside it is equal... therefore the water has no reason to travel in either direction.
No. The solution is already at equilibrium, so there's no need for osmosis.
Yes. It's just that a dynamic equilibrium has been reached and water molecules are entering the cell at the same rate as other water molecules are leaving.
No. Each side of the membrane has the same osmotic pressure.
Yes
To prevent organelles bursting/shrinking. - Osmosic gain or loss of water.
Water moves towards a solution of greater concentration. If the solution is isotonic there will be no net movement.
Cells must be kept in an isotonic solution.Isotonic means there is an equal concentration of solute both inside and outside of the cell.A hypertonic solution means that there is more solute in the solution compared to within the cell. Water will move out of the cell to reach an isotonic state, causing the cell to shrink. That is BAD.A hypotonic solution means that there is less solute in the solution compared to within the cell. Water will more into the cell to reach an isotonic state, causing the cell to swell and possibly burst or 'lyse'. That is also bad.That's why cells must be kept in an isotonic solution.
In this scenario, the cell and the surrounding solution have the same water concentration (both are 35 percent water). This means that the system is in an isotonic state, where the concentration of water inside the cell is equal to the concentration of water outside the cell. In an isotonic solution, there is no net movement of water. Water molecules will move across the cell membrane in both directions, but there is no overall change in the water concentration inside or outside the cell. The cell's volume and shape will remain relatively stable. In summary, if a cell that is 35 percent water is placed in a solution that is also 35 percent water, the net movement of water will be minimal, and the cell will generally maintain its size and shape.
Diffusion occurs in equilibrium, which means the molecules still move in and out of the cell, but the net (overall, total) movement is 0.
An isotonic solution is one in which the ionic environment is similar to that of the cytoplasm. Hence, when a cell is placed in an isotonic solution, there is no net diffusion of water into or out of the cell. The cell remains intact.

To prevent organelles bursting/shrinking. - Osmosic gain or loss of water.
There would be no net movement of water/solutes.This means that movement across the membrane can occur, but the same amount will move inside as out (and vice versa).
The water molecules are at a dynamic equilibrium, which means that equal amounts of water move into and out of the cell at the same time.
Water moves towards a solution of greater concentration. If the solution is isotonic there will be no net movement.
Isotonic solution: A solution that has the same solute concentration as the cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.when a cell is in a isotonic environment , it means the the amount (concentration) of the solutes in the solution and the amount (concentrarion) of solutes in the cell itself is Equal.So both the solution and Cell have EQUAL amount or Equal concentration of SOLUTES (like salt, sugar, Na+ etc) .ExampleIf the cell has 50% salt or any solutesand you place the cell in a solution that has 50% salt or any solutesthen you can say that the cell is in Isotonic Environment. There will be no change in cell's shape.But if cell has 30% salt and you place the cell in a solution that has 70% saltthen the cell is in Hypertonic solution. Then the water will move out of cell into solution to achieve equilibrium through osmosis. the cell will shrink.And If the cell has 80% salt and you place the cell in a solution that has 20% salt then the cell is in Hypotonic solution. Then water will move out of solution and come into cell through osmosis to achieve equilbrium and the cell will swell( cell will be come bigger) .

If you're asking about what the term isotonic means...there are three basic types of solutions- Hypertonic, Hypotonic and Isotonic Hypertonic Solutions are solutions that contain more solute than the other solution in question. Hypotonic solutions are less concentrated with solute than the other solution (When i refer to the "other solution" usually when you talk about isotonic solutions etc, you are talking about it in reference to another solution) Isotonic solutions are solutions that contain an EQUAL amount of solute with the other solution and the solute diffuses equally from one solution to the other... SOrry if anything is innaccurate, but a proper definition (other than mine) shouldn't be hard to get once you understand this...
Because substances move from areas of higher concentration to areas of lower concentration, the water would move either in or out of the cell. In the fresh water, there was a lower concentration inside the cell, so the water moved into the cell. In the salt water, there would be less water on the outside of the cell, so the water would move out of the cell.
Yes if you are speaking about use with blood. An isotonic solution has the same concentration of specific elements as you blood preventing cellular damage. If you used a hypertonic solution all the water would leave the cell and it would crenate. If you use a hypotonic solution water would move into the cell quickly and the cell would burst (lyse).
