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 draw the ciliated epithelial cell, start by sketching a rectangular shape to represent the cell membrane. Add cilia on top, which are hair-like structures that extend from the surface of the cell. Make sure to indicate the nucleus, which is typically oval-shaped and located within the cell. You may also add other features such as the cytoplasm and any other cellular structures visible under a light microscope.
Step 2
Label three parts of this cell on your diagram.
Answer
- Cilia: The hair-like structures that protrude from the cell surface and are responsible for movement.
- Nucleus: The centrally located organelle that holds the cell's genetic material.
- Cell Membrane: The outer boundary that protects the cell and regulates what enters and exits.
