Microtubule Arrangement

The organization of microtubules within a cell, which plays an important role in cell shape, transport within the cell, and cell division.

Flagellum

A long, whip-like appendage that protrudes from the cell body of certain cells and is used for locomotion or sensory functions.

Cilium

One of many short, hairlike structures that project from the surface of some eukaryotic cells and are used for locomotion or movement of materials across the cell surface.
