Here's why:
* Structural Support: Cellulose is a complex carbohydrate that forms strong, rigid fibers. These fibers are arranged in parallel bundles, providing significant structural support in plants.
* Plant Cell Walls: Cellulose is the primary component of plant cell walls, giving them their strength and allowing plants to grow tall.
* Wood: Wood, a key material for building tall structures, is largely composed of cellulose fibers.
