BIOL 212 - Quiz 6 Short Answer Questions
and Correct Answers | Latest Update
How do animals obtain nutrients?
Using directed movement to find food. Then ingest prey and digest it with
their bodies.
What are the traits that make animals unique (i.e., that are not seen in other organisms)?
Muscle and Nervous Cells
What organism is the evolutionary ancestor of animals, and what evidence do we have for this
relationship?
Choanoflagellates. They are identical to "collar cells" in sponges, which is
the basal group of animals.
What phylum is the basal (earliest evolving) group of animals?
Phylum Porifera
What are the characteristics of Phylum Porifera (sponges), and in what ways are organisms in
this phylum simpler than other animals?

Sedentary, filter-feeders, simpler than other animals because they use
collar cells to capture food from water drawn in through pores. They are
also asymmetric and lack true tissue
What type of lifestyle would favor radial symmetry and what type of lifestyle would favor
bilateral symmetry?
Radial symmetry is best suited for a sessile or planktonic lifestyle.
Bilateral symmetry is best suited for an active lifestyle
What is the difference between diploblastic and triploblastic embryonic development
Diploblastic: having two embryonic layers, endoderm (internal organs) and
ectoderm (outer covering and nervous system)
Triploblastic: having a third embryonic layer, mesoderm (body cavity and muscles)
What types of tissues arise from ectoderm, mesoderm, and endoderm in triploblastic
organisms?
Endoderm: internal organs
Mesoderm: body cavity and muscles
Ectoderm: outer covering and nervous system
What are the advantages of having a body cavity?
