Be able to distinguish the difference between a saturated and unsaturated fat. Tell me why 'fluid mosaic' describes a cell membrane. Describe briefly the importance of the cell membrane to the cell. Describe the methods by which substances get into and out of cells. Be able to explain how proteins interact with the cell membrane. Explain what it means for the cell for a cell membrane to be selectively permeable. Be able to identify which types of transport across the cellular membrane require ATP and which do not require ATP. List/identify the main components found in a cellular membrane. What is the effect of placing a red blood cell in an isotonic, hypertonic, or hypotonic solution? Be able to predict what direction water will move across a semi-permeable membrane. Be able to describe the difference between endocytosis, and exocytosis. Differentiate between active and passive transport. Describe how the cell's surface area affects the size of a cell and explain how eukaryotic cells can be bigger than prokaryotic cells. Be able to label the parts of a prokaryotic and eukaryotic (animal) cell on a diagram. List the specific functions of all of the organelles reviewed in class. Be able to predict what would happen if an organelle is not functioning in a cell. Compare and contrast the differences between prokaryotic and eukaryotic cells. Be able to identify which organelles are a part of the endomembrane system. Identify the four types of eukaryotic cell function and the types of organelles that carry out that function. Know what defines an organelle and why they are important in the cell. Explain how actin filament, microtubules, and intermediate filaments differ. Diagram the endomembrane secretory and endocytic pathways. Be able to identify a photograph of each of the stages of mitosis (interphase, prophase, metaphase, anaphase and telophase). Describe events happening during G, S, G2, and M phases of the cell cycle. Describe events happening during prophase, metaphase, anaphase and telophase of the cell cycle.
