Which salt solution would best approximate the water potential in potato cells? (0%, 0.9%, 5%, 10%, or 15%) How do you know this?

Answer 1

The salt solution that would best approximate the water potential of the potato cells would be the solution in which the potato core did not gain or lose much mass. This would indicate that the solution was close to isotonic to the potato cells if there was not a huge lose or gain in mass. To explain how you know this, you would need to understand how isotonic solutions work and how homeostasis is maintained.Use those concepts to explain why a potato core would not gain or lose much mass if it was in an isotonic solution.
