Colony

Final Question

Protozoa that uses flagella to move

ZooFlagettes (ex trypsonoma)

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

Lack rigid cell wall Have a flagella

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

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

What are three ecological roles that protists have in the biosphere?

1. Food source 2. Production of oxygen and carbon dioxide gas through photosynthesis. 3. Kill and eat harmful bacteria
