The transfer of pollen grains to the female reproductive structure, the pistil, is called pollination. This transfer can be mediated by the wind.
The male GA mate in the pollen grain is called the stamen and is usually found in the pistil.
The pollen grain reach the pistil either by self-pollination or by cross pollination by pollinators.
When a pollen grain comes into contact with the stigma, or top of the pistil, it sends a pollen tube down into the ovary at the pistil's base. Fertilization of plants by animals is called pollination.
I think it's Stigma -.-t

Pollen grain
pistil Sperm is formed in the pollen tube while travelling through the style of the pistil.
pollen grains are the powdery pollens in the pollen sacs . Pollen sacs are situated in the anther. For a pistil to develop into a fruit and ovules to mature into seeds, pollen grains must be transfered from anthers to the stigma. This process is called pollination.
the pistil is helpful to plants it gives of hyfro chemicals whic is needed to undergo stimulation
The pollen tube of most seed plants acts as a conduit to transport sperm cells from the pollen grain, either from the stigma (in flowering plants or angiosperms) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms (conifers and gnetophytes).
This tiny grain is called pollen grain.
