A flower is thought to be a branch that has been shortened and the leaves of that branch have been transformed into various parts of a flower. In this case, the leaf-like organs are called flower leaves. Among them, the sepals and petals, which are considered to be accessory organs from a reproductive standpoint, are called bare flower leaves, while the stamens and carpels (the flower leaves that make up the pistil) that are involved in reproduction are called fruit leaves.
