In this scenario, we are examining the relationship between the salt concentration of solutions in the external environment compared to the concentration inside a cell. The terms hypo-, hyper-, and iso- refer to the relative concentrations of solutes (in this case, salt) between the solutions.
Scenario Analysis:
A:
- Outside Solution: 0% salt
- Inside Cell: 1% salt
- Label the solution: Hypotonic (0% salt is less concentrated than 1% salt)
- Water Movement: → (Water moves into the cell)
B:
- Outside Solution: 1% salt
- Inside Cell: 1% salt
- Label the solution: Isotonic (Equal concentration inside and outside)
- Water Movement: 99% (No net movement of water, but water moves in and out at equal rates)
C:
- Outside Solution: 10% salt
- Inside Cell: 1% salt
- Label the solution: Hypertonic (10% salt is more concentrated than 1% salt)
- Water Movement: ← (Water moves out of the cell)
Summary Table:
| Scenario | Outside Solution | Inside Cell | Label the solution | Water Movement | |----------|------------------|--------------|--------------------|-----------------| | A | 0% salt | 1% salt | Hypotonic | → | | B | 1% salt | 1% salt | Isotonic | No net movement | | C | 10% salt | 1% salt | Hypertonic | ← |
