2. Protozoa ProtostomesDeuterostomes Coelomates Acoelomates Mollusca Crustacea Arachnida Insecta Annelida Echinodermata Chordata Vertebrata Tunicata Pseudocoelomates Monera (Bacteria) Hemi- chordata Metazoa Parazoa Eumetazoa Bilateria † Mesozoa † Triploblasts * Diploblasts Arthropoda Cnidaria Ctenophora Radiata*

3. Basics Unicellular  small No organs or tissues (protoplasmic) Found in terrestrial, marine, aquatic and parasitic environments Reproduce sexually or asexually Nutrition: –Autotrophic –Heterotrophic

4. Groups we will talk about Flagellates (Chlorophyta, Axostylata, and Retortamonada) Ciliates (Ciliophora) Amebas (No Phyla) Apicomplexa

5. Outline Movement of Protozoa 1.Amoeboid 2.Ciliary 3.Flagellar 4.Unknown Protection of Protozoa –Ameba

6. Movement of Protists Flagellates (Chlorophyta, Axostylata, and Retortamonada) Ciliates (Ciliophora) Amebas Apicomplexa

7. Movement of Protists Flagellates (Chlorophyta, Axostylata, and Retortamonada) Ciliates (Ciliophora) Sarcodina (Amebas) Apicomplexa Flagellar movement Ciliary movement Amoeboid movement Parasites

8. Amoeba

9. I. Ameboid movement. Ameboid locomotion is used by certain protists and by numerous kinds of ameboid cells that are located within the bodies of most Metazoa.

10. (gel-like) (more fluid) Complex changes in cell fine structure, chemistry, and behavior.

13. Mechanisms of Ameboid movement.

21. HELIOZOANS ACTINOPHRYS SP. I COLLECTED THIS ONE IN WISCONSIN. Axopodia

22. Diversity of Locomotion in Amebas Creeping Rolling Walking Bipedal-stepping Filopodial creeping Typical with lobopodia

23. Movement II. Cilia (Ciliophora)

26. CATTLE RUMEN CILIATES ENTODINIUM CAUDATUM

28. CATTLE RUMEN CILIATES ENTODINIUM CAUDATUM SURFACE ULTRASTRUCTURE

29. Movement of Paramecium

32. What is that?

33. Cilia act like walking legs!

34. Compound Ciliature The function of some cilia is not only movement but feeding Feeding currents

35. Example of ciliates with compound ciliature Vorticella Stentor
