What you need to know

  • Pollination is the transfer of pollen from an anther to a stigma, on the same plant or another.
  • Insect-pollinated flowers are often colourful and scented, make nectar, and have sticky pollen.
  • Wind-pollinated flowers need none of that. They release large amounts of light pollen and have feathery stigmas.
  • Pollen on the stigma can then grow a tube towards the ovule, where fertilisation takes place.
