Answer:-Starch and cellulose are two types of polysaccharides that are found in plants. However, they have different structures and functions. Starch is primarily used for energy storage, whereas cellulose is used for structure and support What is cellulose? Cellulose is made up of a series of sugar molecules linked together in a long chain. Since it is a fiber that makes up plant cell walls, it's found in all plant foods. The main sources of cellulose for industrial processes are wood and cotton [22]. Cellulose is the main component of paper, cardboard, and textiles made of cotton, flax, or other plant fibers. It is also used for the production of fibers, films, and cellulose derivatives. The cellulose fibers obtained from rice and oat husks had a high purity, due to the high cellulose content (above 93%) and low hemicellulose, lignin and ash contents, with a similar chemical composition as commercial cellulose
