Questions

1. What are serial sections and why are they important?
2. What is the relationship between heterochromatin and the synthetic activity of DNA? What is the significance of the nuclear staining patterns that are described as euchromatic and heterochromatic?
3. What is the site of synthesis of ribosomal RNA?
4. What is the relationship of protein molecules to the lipid bilayer in the fluid mosaic model of the membrane?
5. What is the function of mitochondrial cristae? What are cristae morphologically?
6. What is the functional significance of the Golgi complex?
7. How many membranes comprise the nuclear envelope? The wall of a mitochondrion? The cisternae of the Golgi complex?
8. What are the cytological and functional differences between cilia and microvilli?
9. Know the structural characteristics and functional significance of the following organelles and inclusions: nucleus, nucleolus, ribosomes, endoplasmic reticulum (two types), mitochondria, Golgi apparatus, lysosomes, microtubules, cilia, microvilli, glycogen, lipid, peroxisomes. Which of these require more than pure light microscopy for their identification? What additional techniques can be used?

Note: Practice Questions

1. For each laboratory session there will be microscopes set up on the bench in the front of the lab with practice questions.
2. There will also be a question online that you can access through Courseworks following the laboratory session. It will consist of a printed micrograph, and one or more \multiple choice questions
