Answer

  1. Drawing: In the diagram, draw a detailed representation of a ciliated epithelial cell, including the nucleus, cilia, and cytoplasm.

  2. Label three parts:

    • Cilia: These are hair-like structures on the surface of the cell that help in moving mucus out of the airways.
    • Nucleus: The control center of the cell, containing genetic material.
    • Cytoplasm: The gel-like substance where cell organelles are found.

Step 2

State the function of the ciliated epithelial cells in the airways of the human breathing system.
