  2. Transport for 100 • What organelle most often prepares materials for exocytosis? • Golgi apparatus

  3. Transport for 200 • What are the protein-lined pathways called that allow some materials to pass through membranes? • Channel proteins

  4. Transport for 300 • Cytolysis is occurring. Name the type of cell, type of solution, and the direction of flow of water. • Animal cell (no cell wall) • Hypotonic solution • Net movement of water is into the cell.

  5. Potpourri for 100 • What two structures can help cells cope with hypotonic conditions? • Cell Wall • Contractile Vacuole

  6. Potpourri for 200 • What two characteristics make a substance most likely to pass through the cell membrane? • Small and nonpolar

  7. Potpourri for 300 • The light microscopes we use in class have three different objective lenses. What is the sum of the powers of the three objective lenses (not counting the ocular lens). • Scanning 4x • Low power 10x • High power 40x • ---------------------------- • 54x

  8. Organelles for 100 • Predict three problems that would result if the ER stopped working in your cells. • No new phospholipids for cell membrane and other membrane bound organelles. • No processing of proteins into their finished forms. • No detoxification of harmful materials.

  9. Organelles for 200 What structure contains digestive enzymes, and with which type of membrane transport is it most closely associated? Lysosome Phagocytosis. Engulfed materials are broken down by lysosomes.

  10. Organelles for 300 What problem do cells face as they grow larger? The volume (including all the organelles) grows faster than the surface area (represented by the cell membrane). This means that the cell membrane cannot exchange nutrients and waste with the surrounding environment fast enough to supply the cell’s organelles.

  11. Nucleus for 100 • What structure is responsible for making ribosomes? • Nucleolus

  12. Nucleus for 200 • How is RNA able to move out to the cytoplasm from the nucleus? • Through nuclear pores.

  13. Nucleus for 300 • Your friend just discovered a new unicellular organism and claims that it is a prokaryote. What are two characteristics that this organism must show for your friend to be correct? • A lack of nucleus (a nuclear membrane enclosing the genetic material) • A lack of membrane-bound organelles such as mitochondria, chloroplasts, Golgi apparatus, endoplasmic reticulum, etc.

  14. FINAL JEOPARDY • Electron microscopes can create images of specimens with very high magnification and resolution. What are three shortcomings of electron microscopes? • They are expensive. • Images are black-and-white because electrons are used rather than light. • The preparation process kills specimens, so no movement or behavior can be observed.
