1. Taxonomy Understanding relationships

2. Classification Scheme Kingdom Phylum Class Order Family Genus species Class Order Family Genus Family Phylum Class

3. Five Kingdom System Moneran- bacteria & blue-green algae Prokaryote, cell wall, unicell, plasmid, asexual reproduction, E. Coli, Anabeana, bacillus, spirillus, cocci, Protist- Algae, Protozoans Eukaryote, unicell, “catch- all,” lack tissues, asexual reproduction or not Amoeba, Paramecium, Volvox Fungus- Mushrooms, molds, smut, yeast Cell wall of chitin, heterotroph Truffles, bread mold, corn smut, Plant- vascular & non- vascular Cellulose cell wall, chlorophyll, multicellular, sexual reproduction White pine, Trillium, water lily, Animal- vertebrates & invertebrates Lack cell wall, motile, heterotroph, sexual reproduction, Earthworm, sponge, coral, sea bass, human

4. Dichotomous Key for Kingdoms 1. A. Cell wall present..............go to 2 B. Cell wall absent...............go to 3 2. A. Cell wall made of cellulose...go to 5 B. Cell wall not made of cellulose...go to 4 3. A. Tissues absent......Protista B. Tissues present.....Animalia 4. A. Prokaryote.............Moneran B. Eukaryote.............Fungus 5. A. Tissues present.......Plant B. Tissues absent........Protista

5. Phyla of Animalia Porifera(Sponges) Radial symmetry, spongin, pores, two cell layers Cnidarian (coral, jellyfish) Colonial, radial, nematocysts, polyp, medusa, 2 c.l. + jelly Ctenophora (comb jellies) Comb plates with cilia Platyhelminthes(Flatworms) Three c.l., two-way digestion, Bilateral symmetry

6. Three classes of platyhelminthes: Turbellaria, Trematoda, Cestoda

7. Phyla of Animals, con’t Nematodaroundworm 3 c.l., one-way digestion, Rotifera Motile, cilia form a wheel around mouth Arthropods Chitin exoskeleton, Jointed appendages, advanced sensory system, antennae, eyes have many lenses, hearing, distinct body regions, open circulatory Annelida
