Angiosperms (flowering seed plants) have over 230,000 species. There are various types of angiosperms in from the desert to the tropical rainforest. The sizes of the plants vary as well from the duckweed to the eucalyptus tree. Angiosperms have three dominate adaptations, they are known as: flowers, fruits, and broad leaves. (Audesirk, T., Audesirk, G., and Byers, B., 2008)
Lilies have a structural modification to leaves. The leaves develop through the bud structure. The bud promotes cell division and reproduction. Eventually the lily will stop producing leaves and produce petals. The petals on the flower contribute to pollination. The lily is large and colorful so they will attract pollinators. (Gregory)
The pollinators carry their pollen from one plant to another. Flowers and pollinators work with one another so they will be able to survive. The flowers and pollinators benefit from one another; and animals benefit from pollination as well. Pollen consists of rich protein that animals need to survive. Flowers such as lilies produce their own pollen. However, animals assist flowers with large amounts of pollen. Animals have made it possible for flowers to produce smaller quantities of pollen. (Audesirk, T., Audesirk, G., and Byers, B., 2008)
The pollen is transferred through a process called the angiosperm life cycle. There are male and female gametophytes in flowers: ovaries and anthers. Anthers release the pollen and it is carried away by the wind or by pollinators. So, there are two ways the pollen in lilies (or any other flower) can be transferred.
