1. The Path of Life Where do we go from here? From Microbes to Humans

2. Follow The Tree of Life

3. By the end of this lesson, you will be able to: Describe the make-up of the Protista Kingdom Explain the important evolutionary trends that occur in animal evolution Define the animal characteristics Describe the major groups of animals and provide their general characteristics

4. Where do the protists belong? Chapter 20 Unsettled group/No agreement on classification Any organism that is not a plant, animal or prokaryote Eukaryote Mostly single-celled

6. Zooflagellates Animal-like Swim with flagella Mostly live solitary

7. Sarcodines Animal-like Move with extensions of cytoplasm called pseudopods Ex: ameobas

8. Ciliates Use cilia to move and feed

9. Sporozoans Do not move on their own Parasites Ex: Cause malaria

10. Plant-like Protists Unicellular algae Different pigment types Variety of cell wall structures Cause red tides and algal blooms

11. Multicellular algae Plant-like structures Ex: Fucus & Kelp

12. Fungus-like protists Heterotrophs tht absorb nutrients Ex: Sime molds

13. What is an animal? Multicellular Eukaryotes Heterotrophs Lack cell walls Invertebrates (most) or vertebrate

15. Major Animal Evolution Trends: Cell specialization Organization Development of a coelom Body Symmetry Cephalization

16. What is a coelom?

17. What does symmetry mean?

18. What does cephalization mean?

19. Where do you belong? Tissues/Organization? Coelom/Body cavity? Symmetry? Cephalization? Invertebrate or vertebrate?
