Equal sized potato pieces were placed into test-tubes containing equal volumes of different concentrations of sucrose solution and left for 30 minutes. All other variables were controlled.
After 30 minutes, the potato piece in one of the concentrations of sucrose solution had not changed in size.
What can be concluded from this result?
1 There is no net movement of water into or out of the potato.
2 The water potential of the potato is the same as the water potential of the sucrose solution.
3 The concentration of sucrose in the potato is the same as the concentration of the sucrose solution.
