Flower structures are the parts of a flower that play essential roles in reproduction. The main components include the petals, which attract pollinators with their colors and scents, and the sepals, which protect the flower bud before it blooms. The reproductive parts consist of the stamens, which produce pollen, and the pistil, which contains the ovary where seeds develop. Each flower structure has a specific function that contributes to the plant's life cycle. Pollination occurs when pollen from the stamens reaches the pistil, leading to fertilization. This process ultimately results in the formation of seeds, allowing the plant to reproduce and grow new flowers.
