What are the parts of a sunflower and their function?

A sunflower consists of several key parts: the roots anchor the plant and absorb water and nutrients from the soil, while the stem provides support and transports these substances to the leaves and flowers. The leaves are responsible for photosynthesis, converting sunlight into energy. The flower head, composed of ray and disk flowers, attracts pollinators and facilitates reproduction by producing seeds. Finally, the seeds are the reproductive units that can grow into new sunflower plants.
