1. Kingdom Animalia

2. General characteristics Multicellular –Complex body plans –Diverse forms (invertebrates & vertebrates) Heterotrophic –Herbivores –Carnivores –Detritovores Movement (muscle & nervous tissue) Sexual reproduction Embryonic division Unique tissues (except sponges)

4. Cellular --> Cell-Tissue --> Tissue-Organ--> Organ-system Porifera Cnidaria Platyhelminthes Chordata Grantia Metridium Dugesia Perca Parazoa Radiata Bilateria Bilateria Organization in Organismal complexity

5. Body symmetry Parazoa Radiata Bilateria - Asymmetric - No defined tissue/ organs - Cells agregate & differentiate - Cells disagregate & dedifferentiate - Cnidaria - Central axis - Platyhelminthes -->Chordata - Right & left halves - Top & bottom - Better movement than Radiata - Cephalization

6. Development of body cavities Pseudocoel Coelom Endoderm Mesoderm Ectoderm

8. Cellular --> Cell-Tissue -->Tissue-Organ--> Organ-system Parazoa Radiata Bilateria Bilateria Diploblastic Triploblastic - Endoderm - Ectoderm - Mesoderm - Ectoderm

9. PROTOSTOMES Bilateria Development Zygote --> Blastula --> Blastopore --> Archenteron Spiral Mouth Anus Coelom Mesoderm Gut - Platyhelminthes - Nematoda - Mollusca - Annelida - Arthropoda Determinate

10. DEUTEROSTOMES Zygote --> Blastula --> Blastopore --> Archenteron Radial - Echinodermata - Chordata Anus Gut MesodermMouth Anus Coelom
