The word "cellulose" is spelled with three syllables: [ˈsɛljəˌloʊs]. The first syllable is pronounced with the sound of "s" followed by "e" and "l" which have a short, unstressed sound. The second syllable has a long "o" sound followed by "s". The final syllable is pronounced with "s" sound followed by a long "o" sound and "s" again. The word refers to a carbohydrate that forms the major structural component of plant cell walls, and is often used in the production of paper and textiles.
Cellulose is a complex carbohydrate that serves as a major structural component in the cell walls of plants and some algae. It is composed of repeating units of glucose molecules, which are linked together through chemical bonds. Due to its strong and rigid structure, cellulose provides stability and support to plant cells, giving them the ability to withstand mechanical stress and maintain their shape.
In its purest form, cellulose appears as a white, odorless, and tasteless powder. It is insoluble in water and most organic solvents, making it resistant to degradation. This characteristic makes cellulose a highly useful material with various applications.
One of the primary uses of cellulose is in the production of paper and paper-based products. Cellulose fibers are extracted from plant sources, such as wood pulp, and processed into paper through a series of mechanical and chemical treatments. Additionally, cellulose is used in the production of textiles, as it can be spun into fibers and woven into fabrics.
Cellulose is also a significant component of dietary fiber found in plant-based foods. Although humans lack the enzymes required to break down cellulose, its presence aids in digestion by adding bulk to feces and facilitating regular bowel movements.
In summary, cellulose is a complex carbohydrate that provides structural support to plant cells and is widely used in industries such as paper production and textiles. It is insoluble in water and is a vital component of dietary fiber.
A carbohydrate having the same percentage composition as starch, forming the basis of vegetable fiber.

The word cellulose originates from the Latin word cellula, which means small cell or hive. The suffix -ose is a common suffix used in scientific terminology to denote a sugar or carbohydrate. Cellulose is a complex carbohydrate that forms the primary structural component of the cell walls in plants, hence, the name cellulose.
