3.3a Insect Pollination

Describe the structures of an insect pollinated flower and a wind pollinated flower and explain how each is adapted for pollination.

In order for pollination to occur, there needs to be a transfer of pollen grain from the anther of one plant to the stigma of another plant. Insect pollinated flowers use insects to carry pollen grains from one plant to the other. in order to do so, the plant needs to attract insects. they do this by using signals (colour petals, scent)and value (food nectares, pollen protein). The insects then drop off the pollen grains on the next plant it goes to, therefore initiating pollination.
