Yes, molecules still diffuse into the cell and out of the cell, but it happens at an equal rate. The system is said to be at equilibrium, and no change in diffusion is measured because the molecules entering and leaving the cells do so equally.

Does osmosis occur in an isotonic solution?
In an isotonic solution, there is no net movement of water across the cell membrane, as the concentration of solutes inside and outside the cell is equal. Therefore, osmosis does not occur in an isotonic solution.
Why Does osmosis occur if a cell is placed in an isotonic solution?
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.
Does osmosis occur in an isotonic solution, and if so, how does it differ from osmosis in other types of solutions?
Yes, osmosis can occur in an isotonic solution. In an isotonic solution, the concentration of solutes inside and outside the cell is the same, so there is no net movement of water across the cell membrane. This differs from osmosis in other types of solutions, such as hypertonic or hypotonic solutions, where there is a concentration gradient that causes water to move into or out of the cell to reach equilibrium.
What happen to onion cell epidermis if placed in hypertonic solution?
If an onion cell epidermis is placed in a hypertonic solution, water will move out of the cell due to osmosis, causing the cell to shrink and the cell membrane to pull away from the cell wall. This process is known as plasmolysis.
Does isotonic solution cause osmosis?
Yes, isotonic solutions do not cause osmosis to occur as they have the same concentration of solutes as the cell, resulting in no net movement of water across the cell membrane. Osmosis only occurs when there is a concentration gradient that drives the movement of water from an area of low solute concentration to an area of high solute concentration.
What will most likely occur if a cell is placed in an isotonic solution?
When a cell is placed in an isotonic solution, there will be no net movement of water into or out of the cell, as the concentration of solutes is the same inside and outside the cell. This equilibrium maintains the cell's shape and functionality, preventing it from swelling or shrinking. The cell will remain stable, with its internal environment balanced relative to the external solution.
When does osmotic equilibrium occur?
When the water potential gradient evens out, so that the water potential on eithersides of the partially permeable membrane is equal. Also, when something is placed in an isotonic solution ( a solution with the same waterpotential as the organism contains)
What happens to a red blood cell when exposed to isotonic solutions?
When a red blood cell is exposed to an isotonic solution, there is no net movement of water into or out of the cell. This means that the cell maintains its normal shape and volume, as the concentration of solutes inside and outside the cell is balanced.
When osmosis do not occur?
Osmosis does not occur when the concentration of solute is the same on both sides of the membrane, creating an isotonic environment where there is no net movement of water molecules. Additionally, osmosis may not occur if the membrane is impermeable to water molecules, preventing their movement across the membrane.
What are three types of solutions that can occur during osmosis?
Hypotonic solution: when the solute concentration is lower outside the cell causing water to move into the cell. Hypertonic solution: when the solute concentration is higher outside the cell causing water to move out of the cell. Isotonic solution: when the solute concentration is equal inside and outside the cell resulting in no net movement of water.
Does osmosis occur when dried apple slices are placed in distilled water and corn syrup?
Yes, osmosis will occur when dried apple slices are placed in distilled water and corn syrup. The dried apple slices will absorb water in the distilled water through osmosis as water moves from an area of high concentration to low concentration. In the corn syrup, the opposite will happen as water will move out of the apple slices into the higher concentration solution.
What 3 types of solutions will osmosis occur?
Osmosis will occur in hypertonic solutions, where the solute concentration is higher outside the cell than inside, causing water to move out of the cell. It will also occur in hypotonic solutions, where the solute concentration is lower outside the cell, causing water to move into the cell. Lastly, osmosis will happen in isotonic solutions, where the solute concentration is equal on both sides, leading to no net movement of water.
