  1. Activity 5 What Do Specialized Cells Do?

  2. What structures do all cells have? • Which type of structure would a cell have more of if it were specialized for movement?

  3. Read the introduction. • Examine the photos of the specialized cells at the bottom of the page. Discuss your observations with your partner.

  4. Challenge • What are the specialized structures and functions of cells?

  5. Follow the directions on Student Sheet 5.1, “Specialized Cells,” to complete the simulation.

  6. Neuron (Nerve Cell) • Sends and receives signals

  7. Pancreatic Cells • Produces and releases insulin to control blood sugar.

  8. Muscle Cell • Causes contractions for movement • Contains lots of mitochondria

  9. Intestinal Cell • Absorbs nutrients from food as it passes through the small intestine. • Villi – increase surface area so it can absorb food more efficiently.

  10. Macrophage (white blood cell) • Digests microbes as part of the immune system

  11. Sperm • Swim to the egg • Mitochondria power the flagellum.

  12. Analysis 1 • Pick two of the specialized cells that you observed in the computer simulation. For each cell: • Pick one specialized organelle or structure and explain its function. • Explain what would happen to the cell if the specialized organelle or structure were damaged or missing. • Explain what would happen to the organism if the specialized organelle or structure were damaged or missing.

  13. Revisit the Challenge • What are the specialized structures and functions of cells?

  14. Key Vocabulary • cell • microbe • organelle
