Pollination is an important step in the reproduction of seed plants: the transfer of pollen grains (male gametes) to the plant carpel, the structure that contains the ovule (female gamete). The receptive part of the carpel is called a stigma in the flowers of angiosperms and a micropyle in gymnosperms. The study of pollination brings together many disciplines, such as botany, horticulture, entomology, and ecology. Pollination is important in horticulture because most plant fruits will not develop if the ovules are not fertilised
Bees travel from flower to flower, collecting nectar (later converted to honey), and in the process they pick up pollen grains. The bee collects the pollen by rubbing against the anthers. The pollen collects on the hind legs, in dense hairs referred to as a pollen basket. As the bee flies from flower to flower, the pollen grains are transferred onto the stigma of the female flower part.
Nectar provides the energy for bee nutrition; pollen provides the protein. When bees are rearing large quantities of brood (beekeepers say hives are "building"), bees will deliberately gather pollen to meet the nutritional needs of the brood. A honeybee that is deliberately gathering pollen is up to ten times more efficient as a pollinator than one that is primarily gathering nectar and only unintentionally transferring pollen.
Good pollination management seeks to have bees in a "building" state during the bloom period of the crop, thus requiring them to gather pollen, and making them more efficient pollinators. Thus the management techniques of a beekeeper providing pollination service are different from, and somewhat incompatible with, those of a beekeeper who is trying to produce honey.

Plant sex in action! ;-) The fuzzy stigma having done its job in capturing pollen grains from a visiting pollinator, now it's the pollens' turn to grow fertilization tubes down the style to find the ovules below.
This is a Geranium maculatum flower, taken with maximum magnification using the Raynox Macro lens on my PowerShot.

we surveyed heathlands at Lake of Islands in Cape Breton Highlands National Park early in the 2016 field season. Our group of researchers on this trip included (left to right): Caitlin Porter, Emily Walker and Logan Gray. This picture was taken as we came off the trail and arrived back at the truck, first moment of boots -off after a week of backpacking work
Let the fun begin! U.S. Fish and Wildlife staff lead a youth program on pollinators at Sullys Hill National Game Preserve in North Dakota.

Honey Bee collecting some Easter pollen.
There is nothing like standing under a tree fully bloomed in cherry blossoms with hundreds of bees buzzing around.
Taken with a nikon point and shoot just before dusk.It was actually much lighter out than the picture leads you to believe.Photo was only re sized,no other modifications were made.
Insects pollinating a Bishop's Cap flower in a pot in my Sonoran Desert garden.
I am comparing photos taken at almost the same time on the same day by my "Canon PowerShot SX70 HS" zoom camera and my iPhone 7 Plus two-lens camera.
This photo was shot by the Canon camera.
