Chapter 4 Assessment (24/25)
1. As they flow over rotten logs, slime molds appear to lack any partitioning into individual
cells; however, slime molds do become cellular when they change form to produce
spores. In light of the cell theory that "all living things are composed of cells," then
a. these tissues are not living because they are not cellular.
b. these tissues are a bridge between nonliving and primitive living cells.
c. the general concept still holds because these organisms are cellular at specific
stages in their life cycle.
d. this proves that a "vital force" beyond cell chemistry can give life to substances.
2. What is the smallest unit of living matter?
a. nucleus
b. atom
c. cell
d. element
e. Golgi apparatus
3. Which of the following is true regarding the surface area-to-volume ratio needed for cells
to function properly?
a. A large surface-area-to-volume ratio is needed to furnish nutrients to and expel
wastes from the volume (cytoplasm).
b. The surface-area-to-volume ratio changes constantly. Sometimes the surface
area is greater and other times the volume is bigger.
c. The volume of the cell should be larger than the surface area to ensure that all
waste products are effectively removed from the cell.
