Sunflowers maintain their structure primarily through their sturdy stem, which is reinforced by a combination of vascular tissue and rigid cell walls. The stem transports water and nutrients from the roots, providing support and enabling the plant to stand upright. Additionally, the arrangement of leaves and the orientation of the flower head, which follows the sun (a behavior known as heliotropism), help optimize light exposure and enhance structural stability. This combination of anatomical features allows sunflowers to thrive in various environments.
