A plant cell wall's unique ability to expand without weakening or breaking—a quality required for plant growth—is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The new model, created by Penn State researchers, reveals that chains of cellulose bundle together within the cell wall, providing strength, and slide against each other when the cell is stretched, providing extensibility.
