Cotton is the plant that gives fiber from which clothes are made.

Explanation:
Cotton is a type of plant that belongs to the family Malvaceae and is native to tropical and subtropical regions around the world. It is known for its soft, fluffy fibers that grow around the seeds of the cotton plant. These fibers are the primary source of natural fiber used in the production of clothing and textiles.

Cotton fiber is obtained from the bolls of the cotton plant. The bolls are the fruit of the cotton plant, which contain the seeds and the fibers. The fibers are composed of cellulose, a complex carbohydrate that provides strength and flexibility to the cotton fibers. These fibers are arranged in a twisted, ribbon-like structure, which gives cotton its characteristic softness and breathability.

Cotton is harvested by picking the bolls from the cotton plant when they are fully mature. The bolls are then processed to remove the seeds and separate the fibers. This process involves several steps, including ginning, carding, and spinning, which help to clean, align, and twist the fibers into yarn.

Once the cotton fibers are spun into yarn, they can be further processed and woven or knitted into fabrics. Cotton fabrics are highly versatile and can be used to make a wide range of clothing items, including t-shirts, jeans, dresses, and more. Cotton is valued for its softness, comfort, and breathability, making it a popular choice for clothing in both warm and cool climates.

In conclusion, cotton is the plant that gives fiber from which clothes are made. Its soft, fluffy fibers are harvested from the bolls of the cotton plant and processed into yarn, which is then woven or knitted into fabrics for clothing production.
