Question

Biology Bob is angry that Chemistry Carl has sent a vase of red roses to his girlfriend, Phyllis Physics. Bob dumps 10% saltwater into the vase. Rose cells have about 1% salt inside. When Phyllis sees the roses, she is thoroughly unimpressed by Carl and is grateful to have a great guy like Bob. What happened to the rose cells?

A) The rose cells burst, because the saltwater is hypotonic.
B) The rose cells burst, because the saltwater is hypertonic.
C) The rose cells shriveled, because the saltwater is hypotonic.
D) The rose cells shriveled, because the saltwater is hypertonic.

Answer 1

D because there is less salt inside the cell so water will move out in order to create an isotonic solution so the cells will shrivel

Answer 2

The correct answer is option d. The rose cell shriveled, because the salt water is hypertonic.

The concentration of the water added by Bob is higher than that of the rose cells. When the rose cells are exposed to the water having more salt concentration, the rose cell transfer water molecules out of the cells. As a result of water transfer out of the cell, the cells shriveled.
