D) flagellum.
E) intermediate filament.

Question

Quizplus · Accepted Answer

The flagellum is the single structure that allows locomotion in some cells. It is a long, whip-like structure that propels cells through their environment. Histones are proteins that help package DNA, and do not have a role in cellular locomotion. Cilia are short, hair-like structures that can move cells or substances over the surface of cells, but they are not the single structure that allows locomotion in some cells. Microfilaments and intermediate filaments are both components of the cytoskeleton and can provide structural support to cells, but they are not directly involved in cell locomotion.
