b) Brightly coloured petals are to attract honeybees, bats and moths for pollination. This is a characteristics feature of insect and bat pollinated flowers.
c) Smooth and light pollen are suitable for wild pollination, as pollen grains have to float in air and reach to Stigma. Thus light weight will be suitable here.
d) Protruding and movable anthers are to shed pollen grains to outer atmosphere comfortably and transport it through air current. This is found in wind pollinated flowers.
e) Fragrant and nectar are the rewards for the pollinators, these are to attract them for pollination process. This is found in insect pollinated flowers mainly.
