Kingdom: Protista, Genus: Amoeba sp

Pseudopods used for movement.

Contractile vacuole used to pump fluid from cell to outside the body. Used for respiration, excretion, and maintaining osmotic equilibrium.

Food vacuole stores, digests, and distributes food.

Characteristics of Protists
Definition
1. Unicellular
2. Includes heterotrophic, autotrophic, and parasitic species.
3. Have specialized organelles for handling food, water balance, etc
4. Some (radiolarians and formiferans) have tests or skeletons
5. Some possess flagella, cilia, or pseudopodia for movement; some glide on mucous.
Term
Characteristics of Porifera
Definition
1. Multicellular animals, but cellular (not tissue) level of organization
2. Some cells specialized - for support, food capture, etc
3. Includes marine, brackish, and freshwater specimens.
4. Some species use gemmules as a dispersal and overwintering stage.
