Answer:
A typical flower has four main parts—or whorls—known as the calyx, corolla, androecium, and gynoecium (Figure 1). The outermost whorl of the flower has green, leafy structures known as sepals.
Explanation:
The morphology of most flowering plants is based on four types of whorls:
The calyx: zero or more whorls of sepals at the base
The corolla: zero or more whorls of petals above the calyx
The androecium: zero or more whorls of stamens, each comprising a filament and an anther
The gynoecium: zero or more whorls of carpels, each consisting of an ovary, a style, and a stigma
A flower lacking any of these floral structures is said to be incomplete or imperfect.[3] Not all flowers consist of whorls since the parts may instead be spirally arranged, as in the family Magnoliaceae.
For leaves to grow in whorls is fairly unusual except in plant species with very short internodes. Leaf whorls occur in some trees such as Brabejum stellatifolium and other species in the family Proteaceae (e.g., in the genus Banksia). In plants such as these, crowded internodes within the leaf whorls alternate with long internodes between the whorls.
