5. What are the two major functions of the cell membrane?
6. In the diagram below, consider the dots to be molecules of a solute in a water solution. The space between
the dots is water. The cell membrane is the circle. Water can move across the membrane, but the solute cannot.
For each cell system, tell which way the water will move in each diagram – into the cell, out of the cell, or stays
the same.
