This assessment is worth 10 points.

  1. Which is NOT true about the cell theory?   (1 point)

    a.  
    b.  
    c.  
    d.  
    e.  

  2. As they flow over rotten logs as a fluid sheet, slime molds appear to lack any partitioning into cell units; however, slime molds do become cellular when they change form to produce spores. And the surface of some parasitic flatworms and some insect tissues are a "syncytium" or layer of living material that contains many nuclei and cell organelles but lacks partitioning by cell membranes. These tissues consume food and produce wastes. In light of the cell theory that "all living things are composed of cells," then   (1 point)

    a.  
    b.  
    c.  
    d.

    a.  
    b.  
    c.  
    d.  

  9. An amino sugar called N-acetylmuramic acid is an important building block of the cell wall of some bacteria. Penicillin prevents this amino sugar from being incorporated into the bacterial cell wall. Therefore,   (1 point)

    a.  
    b.  
    c.  
    d.  

  10. Most bacteria live in a solution that is hypotonic relative to the cytoplasm of the bacteria. The cell wall of a bacterium is a peptidoglycan polymer that is tightly cross-linked. This would therefore function to   (1 point)
