Cornstalks comprise a central culm (stalk), segmented internodes, and thickened nodes. They facilitate photosynthesis, carbohydrate storage, and lignin synthesis for structural support. Vascular bundles transport water and nutrients, contributing to the plant’s physiology. Practical applications include cornstalk silage (livestock feed), biofuel production, animal feed, and soil amendment. The versatile nature of cornstalks highlights their importance in agriculture and industry.
