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.
If we take a example of cell then if the solution outside the cell containing less solutes as compare to inside of cell then that solution is hypotonic and if the solution outside the cell contain more solute concentration then it is hypertonic solution
The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
The cell will not loose or gain water.An isotonic solution means that the amount of solutes outside the cell is similar or equal to the amount of solutes inside the cell. Water is moving by osmosis both in and out of the cell at equal rates; the net movement of water is zero.A cell will lose water in a hypertonic solution (more solute in the surrounding environment) and gain water in a hypotonic solution (more solute in the cellular environment). Whether or not a solution is hypertonic, hypotonic, or isotonic is relative to the environment in the cell.
A red blood cell will shrink if placed in a solution with a higher solute concentration than the cell. This is because the water inside the cell will move out in an attempt to equalise the concentrations inside and outside the cell.
A hypertonic environment with regard to the cell.

isotonic solution
when a concentration of something, usually water, is the same inside and outside a cell, it is called an isotonic solution. When there is more inside the cell or membrane, but less outside, the solution is hypotonic. when there is more on the outside , it is known as hypertonic. however, it depends what you are describing
surgar will move into the cell
Osmosis, which is the movement of water across a semi-permeable membrane from where it is in high concentration to where it is in lower concentration. The purpose of osmosis is to equalize the concentration of solutes inside a cell and outside a cell.
Isotonic.
If we take a example of cell then if the solution outside the cell containing less solutes as compare to inside of cell then that solution is hypotonic and if the solution outside the cell contain more solute concentration then it is hypertonic solution
A cell is in __________ when solute concentrations inside and outside the cell are equal.?
A condition whereby the concetration of solutes outside the cell balances/equals that inside the cell
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.
Red blood cells do contain some salts and other ions inside the cell. This means that if it is placed in water (assuming that it is deionized and has no solvent in it) the cell will be hypotonic because the concentration inside the cell will be higher than it is outside the cell.
