No, pollination occurs when pollen grains land on the sticky surface of the stigma.
stigma
Pollination
Pollen tube growth occurs after pollination. Pollen grains are deposited on the stigma during pollination, which then germinate to produce pollen tubes. These tubes grow down through the style to reach the ovule for fertilization.
The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollen grains attach to the stigma of a flower's pistil during pollination. The stigma is the receptive part of the pistil where the pollen lands and germinates to form a pollen tube for fertilization to occur.
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
No, pollen grains are not formed within the stigma. Pollen grains are formed in the anthers of a flower's stamen. The stigma is part of the female reproductive structure of a flower, where pollen grains land and germinate to fertilize the ovules.

Pollination
Out of hundreds and thousands of pollen grains produced by each flower a few land on the stigma during pollination and others just wither away.
Pollen tube growth occurs after pollination. Pollen grains are deposited on the stigma during pollination, which then germinate to produce pollen tubes. These tubes grow down through the style to reach the ovule for fertilization.
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
The anther is the part of the stamen that contains the pollen grains. These pollen grains are the male reproductive cells that are essential for the process of pollination.
