A) amoebozoans
B) choanoflagellates
C) rhizarians
D) green algae
E) stramenopiles
Choanoflagellates
Flagellated heterotrophic protists closely related to animals.
Collar
In the context of biology, often refers to a region or structure that encircles another, but without additional context, the term is overly broad.
Flagellum
Long, slender cellular structure used for motility.
- Recognize features that differentiate various protist classifications.
- Identify the phylogenetic relationships between different groups of protists.
