Question 7 • TPS EdX Biology

Which statement best defines a protist ?

Answer
A
an organism that reproduces by spores and feeds on decaying matter
B
a foot-like extension that is used for eating and movement
C
a eukaryote that is either animal-like, plant-like, or fungus-like
D
a long, whip-like extension that is used for movement

Explanation

Protists are eukaryotes—organisms whose cells have a nucleus—that are commonly described as animal-like, plant-like, or fungus-like. A long, whip-like extension is a flagellum, and a foot-like extension is a pseudopod; neither defines all protists. The description of reproducing by spores and feeding on decaying matter fits some fungi, not protists as a group.
