  1. Cellular Structure and Function Section 1 Cell Discovery and Theory The Cell Theory • 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.

  2. Cellular Structure and Function Section 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 CMCD/Getty Images

  3. Utilizes magnets to aim a beam of electrons at Cellular Structure and Function a cell to produce an image Section 1 Cell Discovery and Theory Electron Microscopes • Magnifies images up to 500,000 times the actual size MedicalRF.com/Getty Images

  4. Cellular Structure and Function Section 1 Cell Discovery and Theory Prokaryotic Cell • Simple structure • Contains a plasma membrane • Does not contain membrane-bound organelles Steven P. Lynch

  5. Cellular Structure and Function Section 1 Cell Discovery and Theory Eukaryotic Cell • More complex structure • Contains a plasma membrane • Contains membrane-bound organelles The McGraw-Hill Companies, Inc./Al Telser, photographer

  6. Cellular Structure and Function Section 1 The Plasma Membrane Plasma Membrane • Thin, flexible boundary between the cell and its environment • Allows nutrients into the cell • Allows waste to leave the cell
