  1. Know and recognize the following prokaryotic structures: cell wall, capsules, slime layers, flagella, plasma membrane, cytosol, ribosomes, nucleoid. What are the functions of these structures?
  2. Know and recognize the following eukaryotic structures: cell wall, nucleus, chromatin, nucleolus, nuclear envelope, ribosome, rough endoplasmic reticulum, smooth endoplasmic reticulum, transport vesicles, golgi apparatus, lysosome, peroxisome, central vacuole, food vacuole, storage vacuole, contractile vacuole, chloroplast, mitochondria, microfilaments, intermediate filaments, microtubules, centrosomes, centrioles, cilia, flagella. What are the functions of these structures?
  3. Can you trace how a protein made from a ribosome can travel through the endomembrane system until it is packaged and secreted out of the cell?
  4. What diseases could be associated with lysosomes?
  5. What is the internal structure of a chloroplast like and what does it do?
  6. What is the internal structure of a mitochondria like and what does it do?
  7. What are the following cell junctions like: plasmodesmata, desmosomes, tight junctions, gap junctions?
  8. How are organelles isolated from cells in the laboratory?
