Cotton plant bracts refer to specialized structures found on the cotton plant (Gossypium spp.), which is a member of the Malvaceae family. Bracts are modified leaves that are typically located at the base of flowers or flower clusters, serving various functions such as protection, attraction, or support.

In the case of the cotton plant, bracts play a crucial role in the development and dispersal of cotton fibers, which are actually trichomes or hair-like outgrowths originating from the epidermal cells of the bracts. These trichomes are known as cotton fibers and are composed primarily of cellulose.

The bracts of the cotton plant are relatively large, green, and leaf-like structures. They are typically arranged in whorls around the base of the cotton flower or boll. The bracts enclose and protect the developing cotton fibers, providing a protective covering until the fibers are fully matured.

As the cotton fibers mature, the bracts dry out and become papery in texture. This drying process causes the fibers to expand and separate from the bracts, making it easier for the fibers to be harvested and processed into cotton.

The bracts of the cotton plant can vary in size and shape, depending on the cotton species or variety. However, they are generally broad and ovate in shape, with a pointed tip and a serrated or toothed margin.

Cotton plant bracts are leaf-like structures found at the base of cotton flowers or bolls. They protect and enclose the developing cotton fibers until they mature, at which point they dry out and allow for the easy separation of the fibers during harvesting and processing.
