What does the wind carry from one flower to another?

answ2. Some plants are wind pollinated - the pollen is just spread by the wind. Notably pine trees. But the Beech mast of Nothofagus in the Southern Hemisphere is spectacular.

The stigma of a flower is quite sticky, and there is a good chance that a stray pollen grain will adhere.

Insect Pollination comes next, where an insect is lured (by smell, nectar, colour, shape) to visit the flower for its reward. Many insects actually gather pollen as it is a good source of protein, and they store different pollens separately. Indeed, a foraging bee will take pollen from one plant type only in a journey.

A honey bee transports the pollen in special sacs on its legs.

Bird pollination rather copies that of insects, except the birds are usually only interested in nectar.

In all of these methods, the pollination itself is rather adventitious.

Well the Bee lands on one flower and than it's feet collects pollen and than it goes to the next flower and it goes on and on and on and on!
