Question

what does it mean when a cell is in an isotonic solution? the cell and solution have the same concentration of solutes. the cell has more solutes than the solution.

Explanation:

To determine the correct answer, we recall the definition of an isotonic solution. An isotonic solution is one in which the concentration of solutes (osmolarity) is the same inside the cell and in the surrounding solution. This means there is no net movement of water across the cell membrane due to osmosis. The first option states that the cell and solution have the same concentration of solutes, which matches the definition of an isotonic solution. The second option describes a hypotonic solution (if the solution has fewer solutes than the cell) or is incorrect for isotonic.

Answer:

The cell and solution have the same concentration of solutes.
