Quick Answer

The six phases to a flower's life cycle are the seed, germination, growth, reproduction, pollination and seed spreading. All plants begin life as a seed but flowers are unique in their ability to attract pollinating creatures and spread their seeds.

Flowering plants, also known as angiosperms, begin as seeds that contain a tiny version of the plant itself in embryo form. During germination, the plant pushes out of the seed. The roots begin to push downward searching for water and nutrients as the stem pushes upward toward the surface. The tiny new leaves, called cotyledons, fall off as soon as the first true leaves begin to grow.

Growth is where photosynthesis begins as the leaves collect sunlight and turn it into food for the growing flower. The root system stretches out and develops, and the flower bud begins to form during the growth stage. Within the protection of the bud, a small, complete flower forms.

The reproduction and germination are tied together since flowers that do not contain both male and female parts require pollinators to carry pollen from male to female in order to reproduce. Self-pollinating flowers also benefit from pollination as it allows them to cross-pollinate and grow stronger.

The final stage of a flower's life is the spreading of seeds. Flowers spread seeds in many ways. Some rely on wind, animals or water in order to spread their seeds.
