A cell is in __________ when solute concentrations inside and outside the cell are equal.?
Isotonic, because the cell would neither gain nor lose appreciable amounts of water.
An isotonic cellular environment happens when an equal concentration exists inside and outside the cell.
No diffusion takes place (no solute crosses membrane). The solution is isotonic and is in equilibrium
It is called Isotonic.

Water Movement across a cell membrane is called Osmosis. And it is dependent on the concentration of ions on each side of the cell membrane. If the concentration is higher on the inside of the cell water rushes in to dilute the ion concentration and get it to equal the outside concentration of ions and this is called hypotonic. If the concentration is higher outside the cell water will rush out of the cell to help dilute the concentration outside the cell and get the two concentrations to become equal and is called hypertonic. If the concentration is equal in both outside and inside the cell there will be no water movement and is called isotonic. Osmosis
The solute concentration is equal on both sides of the cell membrane
Osmosis is a phenomenon that helps cells reach equilibrium. If you have a membrane that's only permeable to water and not to, say, a certain solute...and you have too much of the solute on one side, water flows passively to that side. That way, it can make the concentrations on both sides of the membrane more equal.
osmosis is the diffusion of water. In diffusion, substances move from an area of high concentration to and area of lower concentration, or from a hypotonic solution to a hypertonic solution. Free water concentration just refers to the concentration of solute in a solution (in osmosis, water). If the concentration of solute is higher outside of a cell bits of solute will move towards the area of lower concentration: inside the cell. If the concentration of solute is higher within the cell then some solute will leave the cell. Cells "want" to be isotonic, or to have equal amounts of solute both inside and out. When a cell reaches an isotonic state it wants to stay that way, so the water moves across the membrane at the same rate. Hope that helps! Source: AP bio student

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.
There would be no net movement of water across the membrane because the amount of solute inside and outside of the membrane is equal.
Concentration gradient is crucial to the structure of a cell. Cells need to be in an isotonic solution to survive *(unless they are specifically designed cells that are made to deal with being in a non-isotonic solution). Isotonic solution means that the concentration of solute outside the cell is equal to the inside of the cell. The reason being isotonic with their environment is so important to a cell is because of the rules of osmosis. Cell membranes can pass water freely through specific channels that let it in and out. And, because of the rules of osmosis, water wants to be at equal concentration inside and out. The water will move accordingly to try and even out the concentrations of the intracellular environment and extracellular environment. To think of it in a simpler way, it does not want one side of a membrane to be salty and another side to be fresh, it will move so they are both at equal saltiness. Remember that the salt cant move across the membrane, so to even things out the WATER must move. (we are not always dealing with salt when we talk about osmosis, but to learn the principles, we can simplify it and think of solute concentrations in terms of salty or fresh water) So, if a cell is put into HYPERtonic solution, where the concentration of solute outside the cell is much higher than that of inside the cell, it will shrivel. This is because water inside the cell rapidly leaves, to try and make the concentration of solutes inside and outside equal. You can remember this by remembering what happens if you drink salt water. You get dehydrated. Or, if you put a freshwater fish into very salty water, it will shrivel and die. This also explains why you gargle salt water when you have a sore throat- shrivel those bacteria up! On the contrary, if you put a cell in a HYPOtonic solution, (solution where the concentration of solute is very low outside compared to the inside of the cell) the cell will blow up like a balloon. This is because water rapidly flows into the cell to try and make concentrations of solute equal inside and outside. The cells can blow up so big that they can pop, or lyse to use the proper term.
when net solute concentrations are equal on both sides of a semi permeable membrane its called isotonic
When there is a solution on either side of a barrier (membrane for example) withing a cell, the concentrations of said solution will be different on either side of the barrier. Concentrations do not like to be different and will move from high to low until they are equal. For example, there are sodium ions on either side of a cell membrane. the concentration is higher inside, so to make the concentrations equal, some salt ions move through transmembrane proteins from the inside of the cell to the outside. it's called passive because it doesn't use any energy

The water inside the cell goes with the low concentration to reach equilibrium.
