Chapter 4: A Tour of the Cell Guided Reading
Section 4.2
1. Identify the basic features common to all cells
2. Label the prokaryotic cell below – list structure and function.
3. What is the difference between the cytoplasm and the cytosol in eukaryotic cells?
4. Discuss the size of a typical prokaryotic cell to that of a eukaryotic cell.
5. Why is surface area to volume such an important concept as it applies to the size of a cell?
1
6. Discuss how microvilli increase the absorption of nutrients in the small intestines.
Section 4.3
7. For each of the structures below – note the specific structure and the function of the organelle or part of

Label the diagram below showing the relationship amongst organelles in the endomembrane system
Section 4.5
8. Discuss the inverse relationship between the mitochondria and the chloroplasts
9. Give a simplified version of the endosymbiont theory which theorizes the origin of eurkaryotic cells and
their organelles.
Label the diagram of the process involved in the endosymbiont theory.
5
10. How do mitochondria and chloroplast have similarities with bacteria?
11. Continue to give the functions of the cell organelles listed.

Section 4.7
1. Discuss the purposes for the cell wall in plant cells.
2. Identify the composition of plant cell walls
3. How can plant cells with their rigid cell walls communicate with one another?
4. What is the EMC and what are its main components?
7
5. Label the diagram below – for each structure – briefly list its function:
5. What is the main function of integrins in the plasma membrane?
6. How do adjacent plant cells “communicate” with one another by allowing for the exchange of materials?
