Final answer:
Plants use flowers, fruits, seeds, and cones for reproduction.
Step-by-step explanation:
Structures that are used for reproduction in plants include flowers, fruits, seeds, and cones. Flowers are the reproductive organs of flowering plants and produce pollen and ovules which fertilize to form seeds. Fruits are the mature ovaries of flowering plants and contain seeds. Cones are the reproductive structures of gymnosperms, such as pine trees, and contain the seeds. These structures play a crucial role in the reproduction and propagation of plants.
