A cell that is in an isotonic solution is in equilibrium with the solution. What ions and water outside of the cell is the same as the ions and water that is inside the cell. The term -iso means the same.
It is in a Isotonic Solution.
The cell is in a state of equilibrium. Meaning it is in an isotonic solution and there is no net osmotic pressure on the membrane.
Water moves out of the cell in hypertonic solution.
In isotonic solution cells reach a point called dynamic equilibrium.
For hypotonic solution, it means that the solution has lower concentration of solutes (salt, sugar etc) than inside the cell. If it is an animal cell, water will move from the hypotonic solution to inside the cell and the cell will swell and burst open. This is called cytolysis. For the plant cell, water will enter the cell and the cell wall enables the plant cell to swell and become turgid without bursting. For hypertonic solution, it's actually the opposite of hypotonic solution.It actually means that the solution has higher concentration of solutes than inside the cell. For the animal cell, water leaves the cell through osmosis and it will shrink and tiny spikes appear on the cell membrane. This is called crenation. For the plant cell, its cytoplasm shrinks away from the cell wall. This is called plasmolysis. Last but not least, the isotonic solution! This means that the concentration of solutes in the solution is equal to the conc of solutes inside the cell. The result: water moves equally in both direction and cell remains the same size. That's called dynamic equilibrium!
If a cell containing 97% water was placed in a hypertonic solution of 10% salt and 90% water, then the cell would crenate. This occurs due to osmosis. The hypertonic solution will pull out the water which will cause the cell to shrink. It does this to reach equilibrium but equilibrium cannot be attained. The concentration of the hypertonic solution is too great for the cell or Isotonic so the permeable cell will give to the osmotic pressure being greater than turgor pressure; solute and waste will be removed from the cell causing it to shrink in size because the turgor pressure keeps the cell stable.
The cell and the solution will reach equilibrium when they each contain 40 percent water. This equilibrium is achieved through osmosis.
The cell is in a state of equilibrium. Meaning it is in an isotonic solution and there is no net osmotic pressure on the membrane.
a supersaturated solution
When a cell is in a solution that has the same concentration of water and solutes, it is considered isotonic. Water still moves through the plasma membrane, but water enters and leaves the cell at an equal rate-it has reached an equilibrium, and there is no net movement of water.
equilibrium is reaching that state of equal concentration. isotonic is how you describe the cell that has equal concentration.
Equilibrium
It's called osmosis. The salt concentrations inside and outside the cell will "try" to reach an equilibrium, and since the salt concentration outside the cell is higher, water will flow out of the cell, making it shrink.
Water moves out of the cell in hypertonic solution.
