A hibiscus flower is a "perfect flower," meaning it contains both male and female reproductive organs in a single bloom. Its anatomy is divided into non-reproductive structures (for protection and attraction) and reproductive structures (for fertilization and seed production). 

Petals (Corolla): The large, colorful, and showy outer parts of the flower. They protect the delicate reproductive organs inside and are specifically shaped and colored to attract pollinators.

Sepals (Calyx): The green, leaf-like structures at the base of the petals. They support and encase the flower while it is still in the bud stage.

Bracts: A smaller set of modified, leaf-like green structures found directly beneath the sepals.
