Anemophily is a form of pollination whereby pollen is distributed by wind. Unlike entomophilous and zoophilous species, whose pollen is spread by insects and animals respectively, anemophilous species do not develop scented flowers, nor do they produce nectar. Honeybee and bumblebee pollinating a Sedum telephium Pollination is an important step in the reproduction of seed plants: the transfer of pollen grains (male gametes) to the plant carpel, the structure that contains the ovule (female gamete). ... SEM image of pollen grains from a variety of common plants: sunflower (Helianthus annuus), morning glory (Ipomea purpurea), hollyhock (Sildalcea malviflora), lily (Lilium auratum), primrose (Oenothera fruticosa), and castor bean (Ricinus communis). ...

Entomophily is a form of pollination whereby pollen is distributed by insects, particularly bees, moths, and beetles. ... Zoophily is a form of pollination whereby pollen is distributed by animals, particularly by hummingbirds and bats, but also passively by bears, rabbits, deer, and other furred animals. ...

Male and female reproductive organs are generally found in separate flowers, the male flowers having a number of long filaments terminating in exposed stamens, and the female flowers having long, feather-like stigmas. Stamens of the Amaryllis with prominent anthers carrying pollen Insects, while collecting pollen, accidentally transfer it from one flower to another, bringing about pollination The stamen is the male organ of a flower. ...

Pollen from anemophilous plants tends to be smaller and lighter in weight than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher protein pollens from entomophilous flowers are scarce. Also anemophilous pollens may also be inadvertantly captured by bees' electrostatic field. A representation of the 3D structure of myoglobin, showing coloured alpha helices. ...

Almost all pollens that are allergens are anemophilous. Ragweed, the bane of hayfever sufferers, is anemophilous. Its pollen has been found at sea hundreds of miles from its source. Spring hayfever often traces to pollens from birches. An allergen is any substance (antigen), most often eaten or inhaled, that is recognized by the immune system and causes an allergic reaction. ...
