DENDROLOGY

Detailed explanation-1: -Wind pollinator flowers may be small, no petals, and no special colors, odors, or nectar. These plants produce enormous numbers of small pollen grains. For this reason, wind-pollinated plants may be allergens, but seldom are animal-pollinated plants allergenic.

Detailed explanation-2: -Pollen grains of wind-pollinated flowers are produced in large quantities to make sure that at least some pollen grains reach the stigmas of other flowers and successful pollination takes place as many pollen grains are wasted. These pollen grains are light and hence are easily transferred to other flowers.

Detailed explanation-3: -Wind-pollinated flowers don’t need to be attractive to insects, so they are usually small and do not produce nectar or have large colourful petals. The anthers dangle in the breeze, and the pollen is blown away. The pollen grains are very small and light so they are easily carried on the wind.

Detailed explanation-4: -Wind-pollinated flowers do not produce scents or nectar; instead, they tend to have small or no petals and to produce large amounts of lightweight pollen.
