Question

Anemophily is pollination by
A)Air
B)Water
C)Insects
D)Animal

Answer 1

Hint: Wind-pollination syndrome characteristics include a lack of fragrance production, a lack of showy floral components resulting in inconspicuous flowers), decreased nectar production, and the production of enormous amounts of pollen grains.

Complete answer:
A method of pollination through which pollen is spread by wind is hemophilia or wind pollination. Like many trees, such as grasses, sedges and rushes, almost all gymnosperms are anemophilous. The anemophilous pollen grains are light and non-sticky, so that air currents can move them. In order to expose the pollen to wind currents, anemophilous plants have well-exposed stamens and often have a large and feathery stigma to quickly trap airborne pollen grains. Anemophilous pollen are smaller and lighter compared to the entomophilous pollen and has very poor nutritional content for insects.

However, at times when higher-protein pollens from entomophilous flowers are scarce, insects also collect pollen from staminate anemophilous flowers, and the electrostatic area of bees may also inadvertently collect anemophilous pollen. This may explain why its pollen is often found in honey produced during the floral flowering of ragweed, although ragweed flowers are not observed by bees. Bees work actively on other anemophilous flowers, with solitary bees often visiting grass flowers, and larger honeybees and bumblebees often gathering pollen from corn tassels and other grains.

Hence, the correct answer is option (A)

Note: Almost all pollens, which are allergens, come from anemophilous organisms. The grasses (Poaceae) are considered to be the main producers of aeroallergens found in maximum of the temperate regions, which also include the lowland or meadow species which are able to produce more pollen compared to the upland or moorland species.
