SBI4U CHAPTER 2 REVIEW: CELL AND CELL MEMBRANE Cell Organelles vocabulary: eukaryotic, prokaryotic, nucleus (chromosome, nucleolus, nuclear pore, nuclear envelope), endoplasmic reticulum (smooth, rough), endomembrane system, vesicles, Golgi apparatus, lysosomes, peroxisomes, vacuole, chloroplast, mitochondria, cell wall, cytoskeleton, cilia, flagella Cell membranes vocabulary: phospholipid bilayer, glycoproteins, integral proteins, peripheral proteins, semipermeable, channel protein, carrier protein, Cell membrane transport vocabulary: solution, hypotonic, hypertonic, isotonic,passive transport, concentration gradient, diffusion, osmosis, facilitated diffusion, vocabulary: active transport, membrane-assisted transport, endocytosis, exocytosis, phagocytosis, pinocytosis, receptor-mediated endocytosis 1. Describe the function of all the major cell organelles. Be able to label both an animal and a plant cell. 2. Compare the roles and types of organelles in a plant and an animal cell. 3. Chefs often place salad greens in water to make the vegetables crispy. What organelle is principally responsible for the increase in plant cell rigidity? Is this an example of active or passive transport? What type of transport is it? Explain. 4. Why do phospholipids placed in water form bilayers? 5. The cell membrane is often called the “fluid mosaic model”. Explain. 6. Which forms of cell transport require a net input of energy? Which do not? 7. Some molecules require active transport while others can use some form of diffusion. Create a chart to show which molecules use which form of transport. 8. Explain why some forms of transport require energy. 9. Some forms of transport use proteins while others don’t. Explain the different types of proteins that are involved in membrane transport. 10.Draw a diagram of membrane-assisted transport, from the synthesis of a peptide-based hormone on the rough endoplasmic reticulum to its release at the cell surface. 11.Reverse question (9) to show the endocytosis of an enzyme co-factor that is going to be used by the cell’s nucleus.
