Pollination has become a very specialized thing for plants in the rainforest. The Heliconia flower attracts hummingbirds with its sweet nectar. As the hummingbird sucks the nectar out of the flower, the plant dabs a part of its body with pollen. When the hummingbird visits a female plant, it fertilizes it unknowingly depositing pollen in the flower. Many plants that attract hummingbirds deposit pollen on different parts of the bird to prevent cross-pollination (Sayre,29).

Different shaped and different smelling plants attract different animals or insects. Trumpet-shaped flowers attract hummingbirds, and free hanging, night-blooming flowers attract bats. Some flowers even attract male insects by smelling and looking like the female.

The trees, which are more simplistic, allow the wind to carry their pollen.

Some plants use fruit to spread their seeds. When an animal eats fruit, it also ends up eating the seeds. When the animal discharges waste out of its body in another location, the seeds remain fully intact and begin their life in a brand new place.
