Although all flowering plants rely on pollination for reproduction, there is a variation in how plants pollinate. There are two types of pollination called self-pollination and cross-pollination. Self-pollination is the more basic type of pollination because it only involves one flower.
Types of Pollinators. Bees share the job of pollinating. Some plants are pollinated by other animals, wind or water. Plant flowers have adapted to the different pollinators.Some birds, especially hummingbirds, pollinate plants.The plants that attract birds are generally brightly coloured, with red, orange or yellow flowers, but are often odourless, since birds have a poor sense of smell.
