Question

A lab group in biology class wanted to model cell transport using wedges of tubers, an underground stem. The students massed

the tuber slices, placed them into various sucrose solutions, and then let them soak overnight. The masses of the tuber slices were
taken the next day. The data is shown here. What statement is best supported by the data from this experiment?
As sucrose moved out of the tuber cells, the tubers gained mass,
The tubers in the 0.6 molar solution lost the most water from their cells.
The tubers in the 0.8 molar solution gained as much water as those in the
04 molar solution
As the sucrose concentration decreased, the mass of the tubers increased
as water moved into the tuber cells.

Answer 1

d

Step-by-step explanation:

took the test

Answer 2

(D) As the sucrose concentration decreased, the mass of the tubers increased as water moved into the tuber cells.

Step-by-step explanation:

As the sucrose concentration decreased, the mass of the tubers increased as water moved into the tuber cells. The water potential of the pure water is the highest, so water will move into the tuber cells as the water moves from high water potential to lower water potential. Therefore, the answer is D.
