Which structure is thick to protect some of the reproductive structures in flowers

Answer 1

The structure that is typically thick to protect the reproductive structures in flowers is called the calyx. The calyx is the outermost whorl of the flower, consisting of sepals that are usually green in color. The sepals are often thick and leathery, providing protection to the more delicate reproductive organs, such as the petals, stamens, and pistils, which are located inside the calyx.
