1 1. Identify the solute shown in the diagram below, and explain why it is considered a solute.

2 2. Explain how you could: a)decrease the concentration of the sugar solution b)increase the concentration of the sugar solution

3 3. Explain why it is incorrect to say that living things are 72% pure water. Use scientific vocabulary in your answer.

4 4. Explain why cells constantly move solute and water across their membranes.

5 5. Identify the membrane below as permeable or selectively permeable, and explain why. Direction of movement

6 6. Identify a solute molecule that can pass directly through the cell membrane, and explain why it is able to pass directly through.

7 7. Explain why the cell membrane is not directly permeable to glucose, and explain how glucose enters the cell when it is needed.

8 8. Explain why the cell membrane is not directly permeable to Na+ or Cl-, and explain how these substances enter the cell when they are needed.
