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: -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-3: -Final answer: Wind pollinated flowers are small, producing a large number of dry pollen grains.

Detailed explanation-4: -The wind-pollinated flowers comprise light-coloured petals without a pleasant strong smell. The insect-pollinated flowers comprise brightly coloured petals with a pleasant strong smell. In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily.
