Possible short answer questions for Zoology Exam #2.
Selected items from Chapter 7.
A) Describe the three major ‘Animal-like’ groups. Describe ways in which we
can characterize the various animals- i.e. single cell, multi cell, diplo, triplo,
developmental etc.
B) Describe the developmental characteristics of Protostomes and
Deuterostomes.
Chapter 8
C) Describe the characteristics of the Kingdom Protozoa. Is it animal or plant?
Why?
D) Describe the symbiotic lifestyle of the Zooflagellated Protozoa Phylum
Apicomplexa: Plasmodium that causes Malaria.
Chapter 9
E) Describe the evolutionary perspective of the multicellular animal. Be sure
to include theories and ancestral origins.
F) Describe the characteristics of the Phylum Porifera. Include the cell types
found in the body wall and their general function. Also include the various
skeleton structures found in sponges.
G) Describe the general characteristics of the Phylum Cnidaria and its
“alteration of generations”- Describe the reproductive process of
Cnidarians.
Selected items from Chapter 10
H) Describe the evolutionary relationship between the tribloblast acoelomate
body plan, radial diploblastic body plan- Cnidirian and tripoblastic
coelemate body plan.
I) Describe the important evolutionary characteristics of the Triploblastic
Acoelomate body plan.
