The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollen is in the stamen, which is the male part of the flower. After pollenation, it goes to the pistil, the female part. During fertilization, it moves downward, to the ovule, still inside the pistil. There are several stamen on one flower, the exact number depends on the type of flower. They surround the pistil, which is shorter. Sorry if I answered a simple question with an essay. I tend to do that.
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA
1. Many flowers have both male and female parts. So some flowers can indeed pollinate themselves, and the pollen moves from the stamens to the pistil on the same plant. This is called self pollination. Most flowers, however, are cross pollinating. This means the pollen must be carried from the stamens of one plants to the pistil of another plant of the same kind.
Pollination
The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollen is transferred from the stamen (male reproductive organ) to the pistil (female reproductive organ) by various methods such as wind, insects, birds, or other animals. This transfer of pollen is essential for fertilization to occur and for the plant to produce seeds.

Pollination
When an insect like bee's lands on a flower, pollen sticks to it's legs. So when an insect moves to another flower pollen gets on that flower and so on and so on as the insect moves from one plant to another.
Wind moves pollen for some plants like grass and corn. Animal pollinators move pollen for many flowering plants.
