  1. Chapter 7 Cellular Structure and Function Section 1: Cell Discovery and Theory Section2: The Plasma Membrane Section 3: Structures and Organelles Section 4: Cellular Transport

  2. A B C D Cellular Structure and Function Chapter 7 CDQ 1 Chapter Diagnostic Questions If you wanted to see a three-dimensional image of DNA from a live specimen, which type of microscope would you use? scanning electron microscope transmission electron microscope scanning tunneling microscope simple light microscope

  3. A B C D Cellular Structure and Function Chapter 7 CDQ 2 Chapter Diagnostic Questions Which is not a part of the cell theory? Cells are the basic unit of structure and organization of all living things. All living things are composed of one or more cells. Cells arise only from previously existing cells. Cells are produced spontaneously as an organism grows.

  4. A B C D Cellular Structure and Function Chapter 7 CDQ 3 Chapter Diagnostic Questions Which cell organelles are directly involved with the production of proteins? ribosomes, endoplasmic reticulum, nucleus cell membrane, lysosome, Golgi apparatus nucleus, centriole, vacuole endoplasmic reticulum, cilia, mitochondrion

  5. Cell Unit Question #2 “How do the structures of organisms enable life’s functions?”

  6. Levels of organization in a living organism Chemical Cellular Tissue Organ Organ System Organism

  7. Key theme in Biology - the relationship between structure and function, which points to a designer that created each structure for a specific purpose. Card Sort Activity – • Sort cards into groups based on the level of organization. • Fill in chart matching the structures to the proper functions.

  8. Cellular Structure and Function Chapter 7 7.1 Cell Discovery and Theory The Cell: The Basic Unit of Life • All organisms are composed of one or more cells. • The cell is the basic unit of structure and organization of organisms. • All cells come from preexisting cells.

  9. Cellular Structure and Function Chapter 7 7.1 Cell Discovery and Theory Light Microscopes • Utilizes a series of glass lenses and visible light to magnify an image • Magnifies images up to 1,000 times the actual size

  10. Utilizes magnets to aim a beam of electrons at a cell to produce an image Cellular Structure and Function Chapter 7 7.1 Cell Discovery and Theory Electron Microscopes • Magnifies images up to 500,000 times the actual size 9560x Microscopy Links http://biologygmh.com/

  11. Cellular Structure and Function Chapter 7 7.1 Cell Discovery and Theory Prokaryotic Cell • Simple structure • Contains a plasma membrane • Does not contain membrane-bound organelles 11,000x

  12. Cellular Structure and Function Chapter 7 7.1 Cell Discovery and Theory Eukaryotic Cell • More complex structure 400x • Contains a plasma membrane • Contains membrane-bound organelles

  13. A B C D Cellular Structure and Function Chapter 7 FQ 4 7.1 Formative Questions What feature of eukaryotic cells has enabled them to develop more specific functions than prokaryotic cells? nucleus organelles genetic material (DNA) larger cell size

  14. A B C D Cellular Structure and Function Chapter 7 FQ 5 7.2 Formative Questions Which term describes the function of proteins found on the outer surface of the plasma membrane? identifiers receptors supporters transporters
