Flowers and Unusual Plants

What are the parts of a flower?

Sepal—found on the outside of the bud or on the underside of the open flower. It serves to protect the flower bud from drying out. Some sepals ward off predators by their spines or chemicals.

Petals—Serve to attract pollinators and are usually dropped shortly after pollination occurs.

Nectar—Contains varying amounts of sugar and proteins that can be secreted by any of the floral organs. It usually collects inside the flower cup near the base of the cup formed by the flower parts.

Stamen—Is the male part of a flower and consists of a filament and anther where pollen is produced.

Pistil—Is the female part, which consists of the stigma, style, and ovary containing ovules. After fertilization the ovules mature into seeds.
