  1. Cell Theory Pages 169-173

  2. Discovery of the Cell • Mid-1600s scientists begin using of microscopes • Robert Hooke—cork (a plant material) • Called cells—chambers reminded him of monastery’s tiny rooms which were called cells

  3. The Cell Theory • 3 aspects of the cell theory • All living things are composed of cells • Cells are the basic units of structure and function in living things • New cells are produced from existing cells

  4. Categories of Cells • Cells come in a great variety of shapes and sizes • Examples • Nerve cells • Bacteria • Bone cells Muscle cells

  5. Prokaryotic cells • Prokaryotic cells • Do not contain nuclei • Do contain genetic material • Carry out every activity associated with living things • Example--bacteria

  6. Eukaryotic Cells • Eukaryotic cells—larger and more complex • Contain dozens of structures • Contain a nucleus • Genetic material is seperated • Wide variety • Examples—plants, animals fungi and protists
