3.3b Wind Pollination

Structure of wind-pollinated flower + how each is adapted for pollination:
Transfer: pollen grain from anther -> stigma by air + wind.
1. They travel by wind easily as pollen grains have a light weight.
    Most grains have a "wing" feature, which enables them to be transported  more efficiently.
2.  Exposed anthers help, as they hang outwards, more exposed to the wind.
3. Exposed stigmas help as well as they have a large surface area, + a "feather like" structure, having this traps more pollen better.


  1. nice use of a picture and great notes another homework well done.
