Im fairly sure that the "wing" of a pollen grain is there so in spring when the pollen gets blown off by a gust of wind instead of just falling to the ground it floats around and has more chance of landing on a plant of the opposite sex. its the equivillent to a pollinator such as a bee or honeysucker bird which collect the pollen and spread it to other plant so the cycle can continue

They help aid in wind dispersal.
They don't. Pollen is not used to make honey. Bees collect nectar from flowers. When they return to the hive it is regurgutated into comb cells. The heat of the hive, together with bees fanning the nectar cells with their wings, drive off water from the nectar. The result is honey.
An analogous structure is a structure that has a similar function but different components. For example, the wings of a butterfly verses those of a bird. In both cases, the function is flight, but the wings are build differently.
yes it does; for example, the bladder is made of transitory epithelium, which allows it to expand and contract this theory constitutes the idea of anatomy (structure) and physiology (function) Does the shape of a molecule determine anything else such as life span, size, advancement?
Pollination is the process of transferring male pollen grains to the stigma of the plant (either the same plant = self-pollination, or another related plant close by = cross-pollination). The pollen grains germinate and grow down the style of the plant where the fuse with the female ovules, this results in an embryo being formed, which then becomes the seed of the plant. Pollination is aided by various (so called) "agents" or "vectors", these are things that assist in moving the pollen grains from the anther to the stigma. Vectors/ agents include: wind, insects (bees, butterflies, ants, moths etc.) water in some cases, animals (cats, dogs, sheep, cows, humans etc.)
Butterflies have 4 wings.
The rear legs of the bees are hairy. When they enter a flower pollen grain being light attaches itself on the hairy legs. It is transferred to another flower when theres some frequent movement of the bee,either by flaping their wings or walkin in out the flower. This inturn results to cross poliination.
A honey bee carries pollen on its hind legs in a 'honey basket' on what would be knees on a human.

vestigial structures
to walk and fly
The anther produces pollen grains which would be transferred to other plant's stigma which will receive the pollen grains when an insect fly pass it then the pollen grains will be stuck on its wings.
I think as it lands on flowers the pollen sticks to tiny little hairs on its legs.
the structures of a chicken wings and the human arm adapt to served different function
yes yes they do they cover their fairie wings with pollen and sprinkle the land with fairie dust and pollen to produce the beautiful plants and flowers you see each day
The hind wings of a grasshopper, which is it's second pair of wings, is used to help them fly. While the front wings are rigid, the hind wings are more membrane-like and are very colorful.
Dragonfly wings are more like butterfly wings than a robins.
