This process is called pollination. It is an essential step in plant reproduction where pollen grains are transferred from the anther (male part) to the stigma (female part) of a flower, allowing for fertilization and the production of seeds.
stigma
Self pollination is the dropping of pollen on the stigma of the same flower that produced the pollen, thereby pollinating the flower.
Nothjing would happen if a pollen grain from a rose flower fell on the stigma of a lemon flower

The Stigma
when pollen grain are transferred from the stigma the ovule of the flower , whats takes place
Pollination
POLLINATION!
It cannot reproduce.
Pollen is male part of the flower and stigma is the uppermost part of the gynoecium (which is female part). Thus stigma does not produce pollen, rather pollen land on stigma after pollination to fertilize the egg inside the ovary of the flower.
The stigma which is the female part of the flower produces the pollen sex cells and then that gets transfered to another flower
The pollen grains cannot fertilize the flower
It is transferred by wind or bees.
Pollen is transferred by wind, insects, or animals ensuring it does not reach the stigma of another flower. Different plant species have mechanisms in place to prevent self-fertilization and promote genetic diversity. These methods include temporal separation of male and female reproductive organs, physical barriers, and chemical barriers to prevent pollen from reaching the stigma of another flower.
stigma
self pollination means transfer of pollen from the anthers to the stigma of the same flower. Cross pollination means transfer of pollen from the anthers of one flower to the stigma of another flower.
That is called the stigma.
