What is the inflorescence of a sunflower?

The inflorescence of a sunflower (Helianthus annuus) is a type of composite flower structure known as a head or capitulum. It consists of numerous small florets arranged on a single receptacle, with typically vibrant yellow ray florets surrounding central disc florets that are often brown or purple. This arrangement allows for efficient pollination and maximizes the plant's reproductive success. The overall structure resembles a single flower, though it is actually a cluster of many individual flowers.
