Cells as Units of Life

Multiple Choice Questions

1. The Dutch microscopist who sent letters to the Royal Society of London describing his many detailed observations of life, including units later known to be cells, was
A. Anton van Leeuwenhoek.
B. Robert Hooke.
C. Matthais Schleiden.

2. Which of the following is NOT true about the Cell Theory?
A. It states that all organisms are composed of cells
B. It states that all cells come from preexisting cells
C. It states that small organisms can arise spontaneously
D. It is accepted today by biologists as applying to virtually all forms of life

3.  The surface of some parasitic flatworms and some insect tissues is a “syncytium” or living layer that contains many nuclei and cell organelles but is not partitioned by plasma membranes. These tissues consume food, respire, and produce wastes. Since the cell theory states that “all living things are composed of cells” what is the best statement to accompany this question?
A.  These tissues are not living because they are not cellular
B.  These tissues are obviously a bridge between nonliving and primitive living cells
C.  The general concept of “life is cellular” still holds because these organisms still utilize cells sometime in their life, but this shows that plasma membrane partitions can be abandoned in some animals
D.  This proves that a “vital force” beyond cell chemistry gives life to substances

B.  recognizing and communicating between different cells and tissues.
C.  maintaining connections between adjacent cells.

8. In a phospholipid bilayer, the
A. Cholesterol is on the outside and plays a critical role in maintaining the fluidity of the membrane
B. Glycoproteins are on the inside providing a supporting site for adhesive functions
C. Glycoproteins are anchored in the plasma membrane to assist in their transport functions
D. Water-soluble ends are oriented toward the exterior and interior of the cell, whereas the fat-soluble fatty acids are oriented toward the inside of the membrane

9.  Biologists label various carbohydrates, fats and amino acids with radio-isotopes, place them in a cell culture, and allow time for cell metabolism. Then by disrupting cells in a blender and separating out various cell organelles, they find the radioactive molecules can be detected as part of various cellular compounds although visible cell structures appear unchanged. Therefore
A.  these “food” molecules are used only for energy.
B.  most cell components are constantly being broken down and rebuilt.
C.  molecules diffuse at random through the cytoplasm and into cell organelles.
D.  radioactivity has an unusual role in metabolism of living cells.

12.  When water in a cell freezes slowly, sharp crystals spear through the membranes of the cell. The most likely explanation for the bad taste of meat that has “freezer burn” from repeated freeze/thaw cycles is the destruction of
A.  the Golgi bodies and their vesicles.
B.  lysosomes and resultant autodigestion.
C.  rough endoplasmic reticulum causing the release of ribosomes.
D.  the nuclear membrane causing mixing of nucleoplasm and cytoplasm.
