A solution having the same solute concentration as the cell interior is described as

Explanation:
Tonicity describes how a solution affects cell size through osmosis. When a solution has the same solute concentration as the cell’s interior, there is no net movement of water in or out of the cell because the water potential on both sides is equal. The cell remains its normal size, so this solution is described as isotonic. If the outside were less concentrated (hypotonic), water would enter the cell and it would swell; if more concentrated (hypertonic), water would leave and the cell would shrink. An osmotic solution is a general term for any solution that drives osmosis, but it doesn’t specify equal concentrations.
