1. Animals kingdom

2. What are their similarities? What are their differences?

3. Objectives  Name the main characteristics  Explain what symmetry is  Describe what is cephalization  Mentioned the different body plans that animals have  Explain the difference of an open circulatory system vs. a closed one

4. Characteristics  Eukaryotes without cell wall  Multicellular  Heterotrophs  Locomotion

5. Origin of animals

6. Differentiation

7. Specialization

8. Heterotrophic

9. Name the main characteristics of the animal kingdom

10. Recall the levels of Classification

12. Classification; Phylogenetic tree

13. Body Symmetry Animals are classified by different symmetry plans. Asymmetrical Radial Symmetrical

14. Planes

15. Lets do a worksheet on symmetry.

17. Name the 9 phylums as classification taxons.

19. Cephalization Bilateral animals tend to have sensory and brain in the front.

22. Body Plan Most have a body cavity filled with fluid.

24. Classification; Phylogenetic tree

25. Circulatory System Most have a circulation system.

26. Circulatory System  No circulatory system: ex. Sponges  Open circulatory system: ex. Arthropods, mollusks  Closed system: ex. mammals

27. Circulatory System  No circulatory system: ex. Sponges

28. Circulatory System  Open circulatory system: ex. Arthropods, mollusks  Closed system: ex. mammals

29. Circulatory System  Closed system: ex. mammals

30. Invertebrate vs. vertebrates Most have a circulation system.

32. The one thing that all invertebrates have in common is their lack of a backbone; otherwise, they're as different from one another as they are from vertebrates. All vertebrates fall under one phylum, chordata; invertebrates, on the other hand, include over 30 different phyla, collectively accounting for 98 to 99 percent of all known animal species.

33. Phylum Chordata General Characteristics: All chordates have a dorsal hollow nerve tube, a notochord, and pharyngeal gill slits. All vertebrates (members of a subphylum of chordata) have a backbone (spinal column) and a closed circulatory system.

34. Classification; Phylogenetic tree Which phylum is closely related to Chordates?
