To determine how the student would describe the relationship between the solution in the cell and the solution in the beaker, we need to understand the definitions of isotonic, hypotonic, and hypertonic solutions:
- Isotonic: Two solutions are isotonic when they have the same solute concentration, resulting in no net movement of water across the cell membrane.
- Hypotonic: A solution is hypotonic to another when it has a lower solute concentration. In this case, water would move into the cell, potentially causing it to swell.
- Hypertonic: A solution is hypertonic to another when it has a higher solute concentration. In this case, water would move out of the cell, potentially causing it to shrink.
If the solutions in the cell and beaker are isotonic, there would be no net movement of water, meaning solute concentrations are equal. If one is hypotonic relative to the other, water would move in or out, causing a change in cell volume.
Given the options, the correct choice will depend on the specific concentrations of solute in the cell and beaker. Here is how to interpret each statement based on the relationship between the two solutions:
-
The cell and beaker solutions are isotonic to each other.
- This means no net movement of water occurs.
-
The cell and beaker solutions are hypotonic to each other.
- This statement is contradictory; if both are hypotonic, it suggests each has a lower concentration than the other, which is not possible.
-
The cell is hypertonic to the beaker solution.
- This means the cell has a higher solute concentration than the beaker, causing water to move out of the cell.
-
The cell is hypotonic to the beaker solution.
- This means the cell has a lower solute concentration than the beaker, causing water to move into the cell.
To summarize, the answer would depend on the actual concentrations involved. Typically, you would select the appropriate description based on whether the cell is losing or gaining water in relation to the beaker solution.
