Biology 11 Review

1. Features of Kingdom Animalia.

2. Body symmetry

a. Radial symmetry

b. Asymmetry

c. Bilateral symmetry – anterior, posterior, dorsal, ventral

3. Phylum Porifera

a. Examples of organisms in this phylum

b. Special features of organisms in this phylum: i.e. Filter feeds, 2 cell layers but very

simple

c. Digestion, circulation, reproduction, nervous system

d. Anatomy of the sponge – be able to locate and give functions of these parts: osculum,

incurrent pores, spicules, collar cells, amoebocytes, epithelial-like cells

e. Ecological roles of Porifera

4. Phylum Cnidaria

a. Examples of organisms in this phylum

b. Special features of organisms in this phylum: i.e. Cnidocytes, gastrovascular cavity,

incomplete digestive system

c. Feeding, digestion, elimination, circulation, respiration, reproduction, nervous system,

regeneration, locomotion

d. Anatomy of the hydra – be able to locate and give functions of these parts: tentacles,

cnidocytes, mouth, ectoderm, endoderm, gastrovascular cavity

e. Two body forms: polyp and medusa

f. Four (4) classes of cnidarians: Hydrozoans, Scyphozoans, Anthozoans, Cubozoans. Be

able to distinguish the four classes by type of gastrovascular cavity and species example.

g. Ecological roles of cnidarians

h. Evolutionary advances made b the cnidarians compared with the poriferans

5. Phylum Platyhelminthes

a. Examples of organisms in this phylum

b. Special features: 3 cell layers, most are parasitic

c. Digestion, circulation, respiration, excretion, ingestion, locomotion, nervous sytem,

reproduction

d. Anatomy of Planaria – be able to locate and give functions of these parts: dorsal and

ventral sides, anterior and posterior ends, mouth, pharynx, gastrovascular cavity, central

nervous system (brain and nerve cords), endoderm, ectoderm, mesoderm, flame cells.

e. Evolutionary advances made by the flatworms compared with the sponges and

cnidarians

f. What common characteristics do the flatworms share with other higher animals

g. Parasitic forms – flukes, tapeworms

h. Four (4) classes of Platyhelminthes: Turbellaria, Monogenea, Trematoda, Cestoda. Be

able to give an example species of each, and state the basic features that define them.
