Whether waving in the wind or beautifying homes, colorful blooms enrich human life with visual beauty and delightful fragrance. In addition, flowers are often an important part of the celebration of special occasions, and are used to decorate both structures and people.
Flowers have another important function. The bloom is that part of a plant that ensures its survival – its reproductive organ. Flowers reproduce through pollination.
Some flowers contain both male spores (pollen) and female spores (ovules) that can be joined by the wind. Others have either a stamen (male) or pistil (female), and are usually pollinated by birds or insects like bees and butterflies that receive nourishment from the plants they pollinate. Seeds are formed from the union of the spores, which in turn can grow into new plants.
