1. ANIMAL ANATOMY & PHYSIOLOGY ANIMAL FAMILY TREE SPONGES PHYLA

2. ENTRY TASK Use your knowledge of directional terms to relate the structures to each other anatomically in a short sentence Example: toes to ankle The toes are distal to the ankle. Scalp to skull Diaphragm to lung Heart to diaphragm

3. DOMAIN SYSTEM OF CLASSIFICATION

4. 3 DOMAINS OF LIFE Eucarya: Nucleus Linear chromosomes Membrane bound organelles Mitosis Bacteria: Small Simple organelles DNA in a circular loop Strong cell walls Archaea: Small Simple organelles DNA in a circular loop Strong cell walls – different structure No oxygen

5. EUCARYA KINGDOMS

6. ANIMAL PHYLA

7. GUIDING QUESTIONS How are animals divided up into smaller groups? What characteristics set each group apart? How do those group characteristics affect the animals behavior and/or life strategies?

8. ANIMAL PHYLA RESEARCH PROJECT PHYLA Porifera Cnidaria Mollusk Annelid Nematod/ roundworm Arthropod Echinoderm Chordate PRESENTATION DATE Today 9/28 10/12 10/26 11/16 11/30 12/14

9. Examples include fresh water and salt water sponges PORIFORA: OBSERVE & LISTEN

10. BODY SYMMETRY: ASYMMETRIC OR RADIAL SYMMETRY

11. SPECIALIZED CELLS OR TISSUES? ONLY CELLS, NO TISSUES… SPICULE SKELETON SUPPORT CELLS CHOANOCYTES FILTER FOOD

12. REPRODUCTION SEXUAL OTHER & SELF FERTILIZATION ASEXUAL BUDDING & FRAGMENTATION

13. SEGMENTED? NOPE SEGMENTEDSPONGES

14. ONE OR TWO WAY GUT? NO TRUE GUT – FILTER FEEDERS

15. I will grow it back! WHAT IF I LOSE AN ARM?

16. MOVEMENT? ADULTS STATIONARY LARVAE: MOBILE

17. PORIFERA ARE SPECIAL BECAUSE… No true tissues Special cells push water through canals & chambers in sponge to feed cells Host many organisms in their water passages (mini ecosystem)

18. DISSECTING SAFELY Read Along We will review these items EVERY time we Dissect. Keep this Handout in your Class Folder / Binder.

19. DISSECTION EQUIPMENT Hand Lens Dissecting Tray Forceps Dissecting Pins Scissors Probe Scalpel

20. FIELD TRIP! Seattle Aquarium Friday 9/25 Meet @ 10:15am in front of the Aquarium Plan to take about 3 hours Challenge: Find and Observe example organisms from each of the Animal Phyla we are exploring this semester

21. HOMEWORK: ONLY Cnidarian Group Create informative presentation about Cnidarians
