Plant cells ... on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils.

Caption (A) SAXS analysis of fiber cell materials to determine the diameter of each bundle in a different microfibril. (B) Polydispersity analysis of the five samples. Peak positions corresponding ...

stimulus-responsive fibrous structure crucial to many cellular processes including cell division, cytoplasmic streaming, and the alignment of cellulose microfibrils in the plant cell wall.
