Wednesday, November 5th: Multiple Choice (+30-35 questions)Thursday, November 6th: EssayContent to cover: Chapters 6, 7 and 12Chapter 6, A Tour of the CellIdentify the structures and functions of cell organelles.Differentiate between pro- and eukaryotic cells.Identify the structures and functions of the cytoskeleton.Chapter 7, Cell Membrane-Structure and FunctionRecognize the surface features and inter-cellular connections of plant and animal cells.Oligosaccharides/Polysaccharides: Purpose/functionIdentify the components and structure of the fluid mosaic model of cell membranes.Provide the names and a description of each of the transmembrane proteinsChannel, intercellular joining, enzymatic, cell-signaling, glycolipids/proteinsPhospholipidsIntegral proteins/Transmembrane proteinsPeripheral proteinsIdentify molecules that keep cell membranes fluid.CholesterolIdentify methods that cells use for transporting small molecules across membranes.DiffusionFacilitated diffusionOsmosisRecognize the conditions that regulate osmosis and tonicity in cells.I. e, salt sucks; water moves from H ->L concentrations by natureIdentify molecules that easily pass through the phospholipid bilayerIdentify methods that cells use for transporting large and/or charged molecules across membranes.Active TransportChapter 12, MitosisIdentify the reasons why cells need cell divisionIdentify the composition of a chromosome.Chromatin: What is it? How is this different from a chromosome?Single chromosome = single chromatid; Double? Sisters?Recognize the phases of the cell cycle. Identify the stages and characteristics of Interphase.G1SG2Identify the stages and characteristics of Mitosis.Prophase and prometaphaseMetaphaseAnaphase TelophaseRecognize the mechanisms of Cytokinesis.Plants vs. animal cellsRecognize factors that control cell division.MPFCyclinsCyclin-dependent kinaseRecognize that the cell cycle can be impaired/control may be lostCancerDensity-dependent inhibitionEssays:You will answer two questions, of your choice, from four options. Be sure to focus on:the structure of the cell membrane, the stages of the cell cycle, diffusion and osmosis, passive and active transport mechanics ................
