What Class of Phylum Chordata retains a body plan that largely
resembles this ancestral chordate body plan? Describe how this
organism makes its living: Where does it live? How does it
feed?
Phylum Porifera -what kind of body symmetry do they have - what
are the unique structures (why are they in this phylum not another)
-how do they get their food -where are they found -common
examples
The body plan of the tetrapods is based on four
appendages. What are the varied forms that these four appendages
take, and how are they used?
Explain how amphibians represent a shift from water to
land (1) in their own life cycle, and (2) within the evolutionary
history of the vertebrates.
Many frogs hibernate in burrows or at the bottom of
lakes during the winter. How do you expect the fat bodies in the

What are the advantages and disadvantages of the
Arthropod body plan, including the exoskleteon, open circulatory
system and tracheal respiration. Why are they so sucessful in terms
of colonizing many habitats and niches?
How do sponges reproduce?
How do sponges feed?
What is the basic body plan of the cnidarians?
What are the two stages of the Cnidarian life cycle?
Which stage of Cnidarian is sexual and which is asexual?
Name two protostome phyla. What characteristics do these
phyla share?
Briefly contrast the body plan of a basal animal (i.e.
porifera or cnidarians) with that of a chordate.
