Unit 2: The Cell Extras  Study Guide


Chapter 6 9 Review
  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 _ani_6,2 intracellular digestion by (cell eating ), and breaks down damaged organelles by (self eating ).
     
  9. The membrane-bound organelles involved in cellular transport _ani_6,4 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.
       
       
    • 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.
