WebbPollinators carry pollen with them as they move from flower to flower. Their pollination services are essential for plants, including the ones we like to eat. Although honeybees get most of the credit, at least 1,500 insect species pollinate plants in the UK. In some parts of the world, birds, bats and even lizards also get involved. Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a … Visa mer Pollen germination has three stages; hydration, activation and pollen tube emergence.
