Worked Solution & Example Answer:Figure 11 shows ciliated epithelial cells from the airways of a human as seen using a light microscope - Edexcel - GCSE Biology Combined Science - Question 6 - 2021 - Paper 1
Step 1
Draw the cell labelled A in the box below.
Answer
To accurately draw the ciliated epithelial cell labelled A, start with the basic outline of the cell, which typically has a rectangular or columnar shape. Ensure to illustrate the cilia on the top surface of the cell, as these are crucial for its function in the respiratory system. The drawing should be as proportional as possible to reflect the actual structure under a microscope.
Step 2
Label three parts of this cell on your diagram.
Answer
Label the following three parts of the cell:
- Cilia: These hair-like structures should be labelled at the top of the cell, highlighting their role in moving mucus and trapped particles out of the airways.
- Nucleus: This should be marked somewhere in the center of the cell, which contains the genetic material and controls the cell's activities.
- Cytoplasm: Label the area inside the cell membrane, indicating the internal environment where cellular processes occur.
