AP BIOLOGY

Detailed explanation-1: -Unlike the typical insect-pollinated flowers, flowers adapted to pollination by wind do not produce nectar or scent. In wind-pollinated species, the microsporangia hang out of the flower, and, as the wind blows, the lightweight pollen is carried with it (Figure 4).

Detailed explanation-2: -These two agents are light in weight as the air and water cannot carry the heavy pollen. Insects get attracted towards the nectar and flower but here in the wind and the water it does not occur. So, this is the reason why wind pollinated and water pollinated flowers are not colorful and they cannot produce nectar.

Detailed explanation-3: -Both wind and water pollinated flowers are not very colourful and do not produce nectar.

Detailed explanation-4: -Anemophilous, or wind pollinated flowers, are usually small and inconspicuous, and do not possess a scent or produce nectar. The anthers may produce a large number of pollen grains, while the stamens are generally long and protrude out of flower.

Detailed explanation-5: -By contrast, wind-pollinated flowers produce tiny grains of pollen that float on the breeze, with only a fraction of them happening to end up on any pistils. Because the odds of successful wind pollination are long, the plant produces an enormous amount of pollen.
