1. Domain Eukarya Kingdom Animalia

2. Coelom? Body cavity - space between digestive tract wall and body wall, surrounded by mesoderm cells, location of organs Phyla: Mollusca, Annelida, Arthropoda, Echinodermata, Chordata

4. Pseudocoelom? Space around digestive cavity, not surrounded by mesoderm cells Phylum Nematoda

5. gut

6. Symmetry Balance or arrangement of parts asymmetry- no symmetry Porifera radial- wheel plan Porifera, Cnidaria, Echinoderm adults bilateral- 2 sided Echinoderm larva, Platyhelminthes, Arthropods, Annelids, Chordata

7. Protostome? Coelom develops from a solid mass of cells, blastopore becomes mouth Mollusca, Annelida, Arthropoda Mouth

8. Deuterostome? Coelom forms from outgrowth of digestive tube, blastopore becomes anus Echinodermata, Chordata Anus

10. Domain Eukarya Kingdom Animalia

11. Traits Eukaryote Multicellular Heterotroph No cell wall Diploid except for gametes Most internal digestion Most zygotes with developmental stages

12. Animals probably evolved from colonial protists

13. Phylum Porifera Traits Radial or asymmetry 3 layers of cells, no tissues or organs No developmental stages or layers Cellular digestion Water dwelling Examples: sponge

15. Phylum Cnidaria Traits: Radial symmetry Tissues (muscle, nerve) no organs 2 developmental layers (endo & ectoderm) No coelom One opening Tentacles with stinging cells Water dwelling

16. Phylum Cnidaria Examples: coral, hydra, sea anemone, jellyfish

17. Phylum Platyhelminthes Traits: Bilateral symmetry Simple organs and systems 3 developmental layers (endo, ecto, mesoderm) No coelom One opening Examples: planaria, flukes, tapeworms
