Anatomy of a flower

A complete flower typically consists of four main parts, or whorls, arranged in concentric circles on the receptacle—the thickened part of the flower stalk.

Vegetative whorls

These non-reproductive parts help protect the essential reproductive organs.

Calyx: The outermost whorl, composed of individual sepals, which are often green and leaf-like. During the bud stage, the calyx encloses and protects the developing flower.
Corolla: The second whorl, made up of petals, which are typically brightly colored, soft, and thin. Their vibrant hues and sweet fragrance are crucial for attracting pollinators such as insects and birds.

Reproductive whorls

These are the essential organs for sexual reproduction.

Androecium (Male Parts): This whorl is composed of stamens, each consisting of two parts.
- Anther: The sac-like structure at the top of the stamen that produces and stores pollen.
- Filament: A slender stalk that supports the anther.
Gynoecium (Female Parts): This innermost whorl, also known as the pistil, typically consists of three main parts.
- Stigma: A sticky, receptive tip at the top of the pistil that captures pollen grains.
- Style: A long, tube-like stalk connecting the stigma to the ovary.
- Ovary: The swollen, basal part of the pistil that contains the ovules (the egg cells). After fertilization, the ovary develops into the fruit.

Biological function of flowers

The flower's structure and development are a masterpiece of coevolution and adaptation, orchestrated for maximum reproductive success.

Pollination: This is the transfer of pollen from the male anther to the female stigma.
- Biotic pollination: Many flowers use living agents like insects, birds, and bats. They offer rewards such as nectar and pollen to attract these pollinators, with which they have often coevolved to create specialized, efficient relationships.
- Abiotic pollination: Other flowers, often smaller and less showy (like grasses), rely on non-living agents such as wind or water to disperse their pollen.
Fertilization and seed development: Once pollen lands on the stigma, it creates a pollen tube that travels down the style to the ovule.
- In a process unique to flowering plants called "double fertilization," one sperm cell fertilizes the egg to form a zygote (the future embryo), while the other fuses with two other cells to form the nutrient-rich endosperm.
- The fertilized ovules develop into seeds, and the ovary matures into a fruit, which helps in seed protection and dispersal.
