Chapter 2: Cell Structure and Function

Question 1

Hypertonic

Answer 1

solution has more solute, and less water

The 10 mol/L solution is hypertonic to the solution in the bag; net movement of water is out of the bag; cells shrink.

Question 2

Hypotonic

Answer 2

solution has less solute, and more water

The distilled water is hypotonic to the solution in the bag; net movement of water is into the bag; cells swell.

Question 3

isotonic solutions

Answer 3

equal solute, equal water

The solutions inside and outside the bag are isotonic; there is no net movement of water into or out of the bag; no change in cell size or shape.
