pollination
The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollination usually involves pollen moving from the stamen to the pistil, where the pollen grains land on the stigma and travel down the style to reach the ovary. This process enables fertilization to occur and the development of seeds.
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.

When pollen is transferred for the stamen to the pistil, the pollen helps the pistil create a fruit, which contains the seeds a plant needs to be grown from.
The process you're describing is known as pollination, which involves the transfer of pollen from the anther (part of the stamen) to the stigma (part of the pistil) of a flower. Once the pollen lands on the stigma, it germinates and grows a pollen tube down through the style into the ovary, where fertilization occurs. This process is essential for the production of seeds and fruit in flowering plants.
neither, it is made in the stamen
they take pollen from the stamen and move it to the pistil.
The stamen is the male reproductive organ of a flower that produces pollen. Its main function is to transfer pollen to the female reproductive organ (pistil) for fertilization to occur, leading to the formation of seeds.
No, flowers with a pistil but no stamen cannot reproduce on their own. The stamen is needed to provide pollen for fertilization, which is essential for reproduction in flowering plants. If a flower lacks both stamen and pistil, it cannot produce seeds and ultimately reproduce.
The male part of a flower is the stamen. It consists of the anther, which produces pollen, and the filament. The stigma is the female part of the flower, located at the top of the pistil, which receives pollen during pollination.
In wind-pollinated flowers, the filament of the stamen is usually longer than the style on the pistil. This is to ensure that the anthers, which are located at the top of the stamen, are well-exposed to the wind for efficient pollen dispersal. The style, on the other hand, does not need to be as long because wind pollination does not require precision in pollen transfer.
