Bio1151 Chapter 6 A Tour of the Cell
  1. All organisms are made of        , which are either              or             .

  2. Cells are generally              and can only be visualized through microscopes.

  3. Their small size enables them to have a high          area to         ratio, to facilitate the exchange of materials into and out of the cell.

  4. Eukaryotic cells have membrane-bound             and can be grouped into 2 main types: animal cells and plant cells.

    Cells exercise:
  5. The          contains most of the          material in the cell, and is bounded by a nuclear           with many nuclear        .

  6. The endoplasmic            (ER) is continuous with the nuclear           .

  7. The        apparatus is the cell's "Shipping and Receiving Center".

  8. The           contains enzymes to carry out intracellular digestion by               (cell eating ), and breaks down damaged organelles by            (self eating ).

  9. The membrane-bound organelles involved in cellular transport form the               system.

  10.               are the cell's "power plant" and perform cellular              .

  11.               perform                 in some plant cells.

  12. Plant cells also contain a large central          , which stores organic compounds and water.

  13. The               is a network of fibers which provides          for the cell, and enables           .

    •               help maintain cell        , and guide the movement of cell components.

      •        and           use microtubules for motion in some cells.

    •                 called        and         are protein filaments that function in cellular motility, such as the contraction in         fibers.

      • Contraction of actin and myosin            , together with sol-gel reversals, also result in           crawling of a cell through the movements of              .

      • Cytoplasmic            in        cells also involve microfilaments to circulate nutrients among organelles.
