Cotton Plant Ovary is an essential reproductive structure found in the family Malvaceae, which includes the genus Gossypium, commonly known as cotton. It is a part of the female reproductive system of the plant and plays a crucial role in the formation of cotton fibers.

The ovary is located at the base of the flower and is typically flask-shaped or ovoid in appearance. It consists of multiple carpels fused together, forming a compound ovary. Each carpel contains one or more ovules, which are the structures that develop into seeds after fertilization.

The surface of the cotton plant ovary is usually covered with fine hairs known as trichomes, which give cotton its characteristic texture. These trichomes serve as the source of the cotton fibers, which are long, slender, and composed mainly of cellulose.

Inside the ovary, the ovules are arranged in a series of locules, which are chambers that house the developing seeds. The number of locules can vary depending on the cotton species, with some having up to five locules per ovary.

After successful pollination and fertilization, the ovary undergoes maturation and begins to develop into a fruit known as a cotton boll. The boll grows in size and becomes fibrous, with the individual ovules expanding and filling with seed fibers. Once the fibers are fully developed, the boll splits open, allowing the cotton fibers to protrude and be harvested.

The cotton plant ovary is a compound structure consisting of fused carpels that contain ovules. It serves as the starting point for the development of cotton fibers, which are commercially valuable and widely used in the textile industry.
