A flower may comprise four organs made of modified leaves:
- Sepals enclose the flower.
- Petals may be brightly colored to attract pollinators.
- Stamens produce pollen that contain sperm.
- Carpels produce ovaries that contain eggs.
A complete flower has all four basic floral organs.
A perfect flower contains both male and female structures.
An imperfect flower may be
- staminate and contains no carpels, or
- carpellate and contains no stamens.
