What does the stem on a sunflower do?

The stem of a sunflower serves several important functions. It supports the flower head, allowing it to stand upright and maximize exposure to sunlight for photosynthesis. Additionally, the stem transports water and nutrients from the roots to the leaves and flower, playing a crucial role in the plant's overall growth and health. Lastly, it provides structural stability, helping the sunflower withstand wind and other environmental factors.
