Plants can’t move around. So how do you think they spread their pollen to make seeds? Most plants use the wind or animals to help them pollinate.
All grasses and many trees, such as hazels and birches, scatter their pollen on the wind. The anthers of these plants hang out of the flower so that a puff of wind can carry away the pollen. The stigmas of these plants also hang out of the flower. They can catch the pollen as it blows past.
Insects, birds, and bats help spread the pollen of some plants. The flowers of these plants attract the animals. Many such flowers are full of sweet-tasting juice called nectar that bees and other animals like to eat. Some flowers “advertise” their supply of nectar with strong scents and bright colours.
When an animal visits a flower to sip the nectar, pollen brushes off onto its body. Then, when it visits the next flower, the pollen on its body brushes off into that flower.
