VENN DIAGRAM ACTIVITY:
ON YOUR PAPER: Using a Venn Diagram, list similarities and differences between active and passive transport.
Check Your Understanding
1. How can you determine if a type of transport requires energy?
2. How are photosynthesis and cellular respiration similar and different?
3. Why does passive transport not require energy?
Free Response: Freddie is a sunfish that lives happily in a freshwater lake. He enjoys his isotonic environment. Unfortunately, pollution from runoff is changing the concentration of solutes in Freddie's lake. The lake water environment is becoming hypertonic to Freddie's cells. Draw a diagram illustrating Freddie in an isotonic environment, use arrows to show the movement of water. Draw a diagram illustrating Freddie in a hypertonic environment, use arrows to show the movement of water.
