Which of the following is responsible for the process of filter feeding in a sponge?
a. flame cells
b. cnidocytes
c. collar cells
d. mesoglea
All of the following are true of Ctenophores except:
A. Some species have long tentacles
B. They catch food with stingers
C. They move with tiny rows of cilia along their outsides
D. They are diploblastic
1. Cite 5 characteristics of sponges:
2. Which characteristics are unique to ctenophores?
3. Cnidarians are diploblastic, possessing an ectoderm and endoderm. Name the
gelatinous nonliving material found between these two tissues. What cells are found
within this gelatinous tissue? List the functions of these cells.
4. Polyp body consists of a tubular sessile body. True or false?
5. Define radial and bilateral symmetry, and protostomes and deuterostomes:
6. The presence of two different body forms, or dimorphism, is seen in the phylum
Cnidaria. The
form resembles an "upside-down cup" with
tentacles, and the
body form consists of a tubular sessile body.
Hydra is an example of the
body form, and a jellyfish is an
example of the
pody form.
