Biology 1060 Chapter 6 A Tour of the Cell Reading, Writing, Reflecting Optional Reading Assignment: pp. 92-93 – Before beginning the reading, write the adjectives that you use to describe scientists Answer the following questions in a 250 word, printed paper due next class (10 extra points): – What adjectives are used in the article to describe scientists? – Describe how medicine and physiology are related – Describe the effect of the structure and function of aquaporins and the effect of their malformation Cells and Microscopes Discuss the importance of cells – Describe how diverse cells are related Compare the largest and smallest cell Compare and contrast the benefits and problems associated with each type of microscope Cell Variety Compare and contrast prokaryotic and eukaryotic cells Discuss the importance of surface area-tovolume ratio and its implications for cell size and functions Give examples of cells with various surface area-to-volume ratios Eukaryotic Cell Distinguish among the types of eukaryotic organisms Make an analogy that gives insight into the cell and the organelles within it Compare and contrast plant and animal cells Nucleus and Ribosomes Describe the structure and contents of the nucleus Discuss the synthesis of ribosomes and their function and state where each occurs Distinguish between DNA, chromatin, and chromosome Endomembrane System Describe the components of the endomembrane system Compare and contrast the types of endoplasmic reticulum Compare and contrast the function of the smooth endoplasmic reticulum and the rough endoplasmic reticulum Golgi Apparatus Describe the structure of the Golgi apparatus Describe the cisternal maturation model of Golgi function Describe how Golgi products are sorted and reach their destinations Scientific Inquiry p. 123 Lysosomes and Vacuoles Discuss the function of a lysosome – Describe the mechanisms that protect it and the cell from destruction Describe the functions of various vacuoles and the organisms having each type Discuss the properties and function of the central vacuole and in which organisms it is important Mitochondria and Chloroplasts Describe the characteristics common to both mitochondria and chloroplasts Describe the structure of a mitochondrion – Relate mitochondrial structure to its function Describe the structure of a chloroplast – Relate chloroplast structure to its function Plastids and Peroxisomes Name and describe the various plastids – Name the organisms possessing plastids Discuss the function of peroxisomes – Describe their importance to the cell Cytoskeleton Define cytoskeleton – Give examples of cytoskeletal functions Discuss microtubule structure and function – Explain the motion of cilia and flagella Describe actin microfilaments – Explain their roles in the cell Describe intermediate filaments – Give examples of their rolls in cells Evolution Connection p. 123 Extracellular Materials Describe the structure and functions of the plant cell wall – List the types of organisms with cell walls Describe the components of the extracellular matrix of animal cells – Discuss how the ECM contributes to the cell Describe the structure and functions of intercellular junctions and where each is found Emergent Properties of Cells Discuss “The cell is a living unit greater than the sum of its parts”.
