Sunflower with stem and leaves

The sunflower exhibits a predominantly yellow ray floret arrangement surrounding a dark brown disc floret center. The petals are elongated and numerous, radiating outwards. The stem is a uniform green and supports several large, lanceolate leaves with discernible venation. The leaves are positioned alternately along the stem. The model appears to represent the sunflower's function as a flowering plant, likely for visual display or educational purposes.
