The structure that is thick to protect some of the reproductive structures in flowers is called the sepal.
The structure that is thick to protect some of the reproductive structures in flowers is called the sepal. The sepals are usually green and form the outermost whorl of floral parts, collectively known as the calyx. They are typically leaf-like structures and serve as protective coverings for the developing flower bud. The main function of the sepals is to provide support and help shield the delicate reproductive organs of the flower, such as the petals, stamens, and pistils, during the early stages of flower development.
