Question 6

	1.	Heterotrophic – cell walls – hair-
	2.	Photosynthetic – flagella – hair-
	3.	Brown or golden – photosynthetic structures – amoeba-
	4.	autotrophic – body forms -- pennate or centric-

Question 7

Amoebozoans include both _________ and __________. The second group was once classified as __________. But are now placed in this clade because among other characteristics they are __________ (mechanism of nutrition) like amoeba.

	1.	Red algae and Green algae – plants autotrophic
	2.	Zygomycota and Ascomycota – fungi -- heterotrophic
	3.	Slime Molds and Oomycetes – fungi -- heterotrophic
	4.	Amoebae and Slime Molds (mycetozoans) – fungi and animals – phagotrophic.

Question 8

The clade Euglenozoa includes organisms such as Trypanosoma and ________ a common type of structure for locomotion.

	1.	Euglena with a flagellum
	2.	Paramecium with cilia
	3.	Plankton in fresh water or oceans
	4.	The vertebrae hosts of these organisms

Question 9

Table 1 on p. 63 outlines four Supergroups, of which one is the Alveolates. Identify two groups within the Alveolates and their shared common characteristics.

	1.	2. Formaniniferas and Radiolarians with a test shell
	2.	1.Ciliates and Dinoflagellates with alveoli sacs below the cell membrane
	3.	4. Euglena with flagella for locomotion
	4.	3. Red and Brown algae with air sacks for flotation

Question 10

The idea of evolutionary convergence among other ideas is demonstrated in this lab (and others) by _________

	1.	Characteristics of organisms in one clade are shared with organisms in other groups or clades.
	2.	The fact that some protist lineages are ancestors of multicellular organisms such as plants and animals.
	3.	Characteristics common to all Protists.
	4.	Methods of locomotion and nutritional strategies are unique to protists.
