Possible short answer questions for Zoology Exam #2.
Be sure to review ppt notes on Animal diversity, and Animal Form and
Function for 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 characteristics of the Phylum Porifera and include major body
forms. Include the cell types found in the body wall and their general
function. How do they gather nutrients from there surroundings? Explain.
F) Describe the general characteristics of the Phylum Cnidaria and its
“alteration of generations”- Describe the reproductive process of
Cnidarians.
Selected items from Chapter 10
G) Describe the evolutionary relationship (theory) between the radial
diploblastic body plan- Cnidirian and tribloblast acoelomate body plan i.e.
Platyhelminthes.
H) Describe the life cycle of Class Trematoda – Chinese Live Fluke. Be sure to
include the different stages of development and all possible hosts.
