44. ZooFlagettes (ex trypsonoma)

45. Some scientists have problems classifying Euglenoids as plant-like protists. What characteristics do Euglenoids have that cause these problems?

46. Lack rigid cell wall • Have a flagella

47. List the four phyla(or groups) of protozoans, explain the type of movement they exhibit, and give an example of an organism that belongs to each group

48. 1. Sarcodina—Move using blob, foramniferans • 2. Zooflagellates – have one or more flagella for Movement, Trichonympha, Trypanosoma • 3. Ciliates(Ciliophora) – move by tiny hair-like structures called cilia, Paramecium • 4. Sporozoans – are parasitic and lack structures for movement. plasmodium, malaria
