J1. Identify and list the characteristics of a member of the animal family.
Multicellular, no cell walls, heterotroph (eat food), can move (at some stage), have specialized cells.
J2. Describe the animal adaptations of asymmetry, radial symmetry and bilateral symmetry. Give an example of each.
- Asymmetry: no shape (sponges)
- Radial: circular body (jellyfish)
- Bilateral: left/right sides (humans, worms)
J3. Compare and contrast acoelomates, pseudocoelomates, coelomates.
- Acoelomate: no body cavity (flatworms)
- Pseudocoelomate: partial cavity (roundworms)
- Coelomate: true cavity (earthworms, humans)
J4. Describe the characteristics of those in the Phylum Porifera by describing how sponges have adapted to the aquatic environment.
Asymmetrical, no true tissues, filter feed through pores, water flows out osculum, simple cells.
J5.Describe the characteristics of those in the Phylum Cnidaria by describing how jellyfish and anemones have adapted to the aquatic environment.
Radial symmetry, tentacles with stinging cells, one opening (mouth/anus), simple nerve net, live in water.
J6. Describe the characteristics of those in the Phylum Platyhelminthes by describing how flatworms have adapted to wet or moist environments.
Flat body (for diffusion), bilateral symmetry, simple organs, live in moist environments, many are parasites.
J7. Describe the characteristics of those in the Phylum Nematoda by describing how roundworms have adapted to their biomes.
Tube-shaped, pseudocoelom, complete digestive system, tough outer cuticle, live in many environments (soil, inside hosts).
