A flower is a small plant that contains: Pollen, Nectar, and usually pettals.

They can only grow in mild conditions and die out during the winter seasons. The food for the low level consumers, and require to be pollenated. To get pollenated they must first attrach said pollenators, they do this by the colorful pettels, the lure of nectar, and other bright colors.
After they are pollnated they'll grow their seeds and drop their pettles, The seeds will grow and be ready to travel. They travel by either hitch hiking a ride on some animals, travling by the wind, or by water until they reach land.
Once they reach land they will start to grow into a new flower.

The primary purpose of a flower is reproduction. Pollination is the movement of pollen from the anthers to the stigma. Normally pollen is moved from one plant to another, but many plants are able to self pollinate. The fertilized ovules produce seeds that are the next generation. Sexual reproduction produces genetically unique offspring, allowing for adaptation. Flowers have specific designs which encourages the transfer of pollen from one plant to another of the same species. Many plants are dependent upon external factors for pollination, including: wind and animals, and especially insects. Even large animals such as birds, bats, and pygmy possums can be employed. The period of time during which this process can take place (the flower is fully expanded and functional) is called anthesis
