Flower: Generally the most visible characteristic of a plant, the flower is an organ made of very specialized parts, related with sexual reproduction. Some plants produce flowers with only male organs (stamens) or female organs (pistils). These parts are generally surrounded by a ring of colored petals and green sepals. In the majority of plants, a flower has both male and female organs; however some species have male flowers and female flowers, like the begonia: the male flowers have a series of brightly colored petals with stamens full of pollen, whereas the female flowers have a large winged sac of seeds, behind the petals.
