Spirochetes, Myxobacteria, and Cyanobacteria

[go to this section in the Guide]
Chapter Seven: The Classification of Unicellular Organisms


Question 1
 Spirochetes are classified under kingdom
   1.  Plantae
2.  Monera
3.  Protista
4.  Fungi
 

Question 2
 Not all spirochetes have to be
   1.  heterotrophic
2.  aerobic
3.  spiral-shaped
4.  prokaryotic
 

Question 3
 What are axial filaments?
   1.  special flagella which hold a spirochete in a spiral shape
2.  organelles which spirochetes use to digest food particles
3.  structures which cause spirochetes to grow
4.  types of mitochondria which spirochetes use to store starch
 

Question 4
 One aspect of myxobacteria which makes them different from many other unicellular organisms is that they
   1.  obtain food from the environment
2.  do not have membrane-bound organelles
3.  generally live in soil rather than in water
4.  require oxygen for respiration
 

Question 5
 The name myxobacteria is derived from their
   1.  unusual method of reproduction
2.  use of flagella
3.  possession of a nucleus
4.  secretion of mucus
 

Question 6
 The large structure which myxobacteria form together when reproducing is called a
   1.  division cavity
2.  fruiting body
3.  reproduction colony
4.  mitosis cluster
 

Question 7
 The collections of cells which the large structures of myxobacteria (mentioned in the previous question) release are called
   1.  cysts
2.  vesicles
3.  cilia
4.  stigmas
 

Question 8
 Cyanobacteria are often considered to be one of the most advanced types of prokaryotes because they
   1.  have linear DNA
2.  use histones to help package their DNA
3.  have speciliazed membranes for photosynthesis
4.  possess membrane-bound organelles
 

Question 9
 Structures which cyanobacteria lack but which most other prokaryotes have are
   1.  flagella
2.  membrane-bound organelles
3.  nucleic acids
4.  ribosomes
 

Question 10
 One characterstic of cyanobacteria that does not vary is that they are
   1.  aerobes
2.  anaerobes
3.  autotrophs
4.  heterotrophs
