What is the main component of natural fiber?

Explanation:
The main component of plant-based natural fibers is cellulose. Plant cell walls are built primarily from cellulose, a long chain polymer of glucose that forms crystalline microfibrils. These cellulose microfibrils provide the tensile strength and stiffness that give natural fibers like cotton and flax their characteristic strength and fiber integrity. Hemicellulose and lignin are also present in plant fibers, but they are secondary contributors that influence properties such as flexibility and binding within the cell wall, not the primary load-bearing component. Starch, on the other hand, is a storage carbohydrate found in seeds and tubers rather than a structural part of mature plant fibers. So the best answer is cellulose.
