Can occur by insect or wind cross pollination - transfer of pollen from the anther of one flower the stigma of another plant self pollination - transfer of pollen from the anther of one flower the stigma of the same flower of the same plant 2 of 4 Wind pollination structures petals - doesn't have any petals as it does not need to attract any insects stigmas - hang out of flower and are feathary. They have a large surface area so they can catch onto pollen stamens - hang out side the flower for more chance of pollen being carried by wind pollen - grains and light and smooth to enable them to be carried through the air nectar - no nectar as it does not need to attract insects scent - no scent as it does not need to attract insects 3 of 4 Insect pollination structures petals - bright and colourful to attract insects stigmas - short and inside the flower stamens - short and inside the flower pollen - grains are sticky so they can stick to the insects body easily nectar - produced in nectary to attract bess scent - smells nice to attract bees 4 of 4
