Wind-pollinated flowers usually have ____ and ____ petals.
A
big ____ bright
B
small ____ bright
C
big ____ dull
D
small ____ dull
Explanation: 

Detailed explanation-1: -Flowers pollinated by wind are called Anemophilous flowers. Wind pollinated flowers have small and dull petals. They don’t have a sweet scent and bright coloured petals to attract insects. Wind pollinated plants produce more pollen to increase the chances of pollination.

Detailed explanation-2: -Anemophilous, or wind pollinated flowers, are usually small and inconspicuous, and do not possess a scent or produce nectar.

Detailed explanation-3: -Wind-pollinated plants don’t normally have flowers, but when they do they are small, don’t have perfumes or nectar, produce large amounts of light pollen, have stamens and stigmas exposed to air currents to either catch or distribute pollen and don’t normally have flower petals.

Detailed explanation-4: -Wind pollinated plants are adapted in a way so that they can allow the wind to transfer their pollen grains from anther to stigma. These types of plants are not brightly coloured and are very dull because these features of plants are useless in case of wind pollination.
