Lily plants belong to a large group of plants called angiosperms. This means that they grow flowers to reproduce. Each flower contains the necessary sex organs to produce seeds, thereby continuing the life cycle.
The life cycle of a lily flower begins with a seed. Once mature, the plant reproduces by growing a flower, which is the sexual part of the plant that produces seeds.
Male Sex Organs
The male sex organ is called the anther, and there are several in each lily flower. The anthers produce pollen.
Female Sex Organs
The female portions of the flower are called the stigma, pistil and ovule. The ovule contains the unfertilized ova of the plant.
Pollination is accomplished when pollen grains, the male gametes of the plant, are transferred to the stigma by an insect or other physical action.
The pollen grains come in contact with the stigma and stick to it. Pollen travels down a path called a pollen tube through the pistil into the ovule to fertilize the ova.
Seeds form in the lily flower. As the seeds mature, the flower dies, and a seed pod grows. The pod eventually releases its seeds.
