Stamen

Some plants have brightly colored flowers to attract animals and have nectar deep in the flower, so animals must brush against the stamens while getting nectar.

Some plants produce sweet fruit that animals will eat, and then animals transport seeds. When the animals release the seeds, they also supply fertilizer.

Some plants have sticky burrs so when animals walk by, the burrs stick to them and the seeds are transported. When the seeds are released, they might have a better chance of survival if the area is less crowded.

Some plants grow very tall so animals can see them better.
