Final answer:
Beta-glucose polymerizes to form cellulose, a linear and insoluble polymer which is a key structural component in plant cell walls.
Step-by-step explanation:
β-Glucose polymerizes to form cellulose, which is an unbranched and insoluble polymer. Cellulose is a structural polymer of glucose units found in plants. It is composed of glucose molecules linked together through β-1,4-glycosidic bonds, providing a linear structure that facilitates extensive hydrogen bonding between adjacent chains.
This tightly packed arrangement contributes to cellulose's insoluble nature and its mechanical strength, which is essential for the cell walls of green plants. Unlike starch or glycogen, cellulose does not branch out or store energy; instead, it forms a rigid framework that plants rely on for support.
