DENDROLOGY

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: -Insect-pollinated flowers produce nectar in order to attract pollinators, such as fruit-eating bats, hummingbirds, sunbirds, and insects. Nectaries are usually located at the base of the flower stamens, which draw animal visitors into contact with the pollen to be transferred.

Detailed explanation-3: -These flowers are not attractive, non-scented and colorless because here there is no use of color and scent which is usually required to attract flies, bees, other insects etc. These flowers do not possess nectar. Hence, the correct answer is option (B), wind pollinated flowers are small, non-scented and colorless.
