Pollination
The delivery of pollen to the stigma of the carpel is called pollination. This can occur through various methods, including wind, water, animals, or self-pollination. Once pollen lands on the stigma, it can germinate and fertilize the ovules to form seeds.
During fertilization in flowering plants, the stigma of the pistil receives the pollen. The stigma is the sticky top part of the pistil, which captures and holds the pollen grains. Once the pollen lands on the stigma, it germinates and forms a pollen tube that travels down the style to reach the ovary, where fertilization occurs.
A stigma is the part of a flower's female reproductive system that receives pollen during pollination. Once pollen lands on the stigma, it begins the process of fertilization that leads to seed formation. The stigma plays a crucial role in facilitating the transfer of pollen to the ovary of the flower.
Pollen is transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower through pollination. Once the pollen lands on the stigma, it forms a pollen tube that grows down through the style and delivers the sperm cells to the ovule for fertilization.
The structure that grows out of the pollen grain and into the stigma is called the pollen tube. Once the pollen grain lands on a compatible stigma, it germinates and forms this tube, which extends down through the style to reach the ovule in the ovary. The pollen tube carries the male gamete (pollen nucleus) to the egg cell for fertilization. This process is essential for sexual reproduction in flowering plants.

When stigma and pollen develop, they enable the process of pollination to occur. The stigma is the part of the pistil that receives the pollen, while the pollen contains the male gametes needed for fertilization. Once the pollen lands on the stigma, it can germinate and grow a pollen tube to transport the male gametes to the ovule for fertilization.

The stigma, part of the female reproductive structure of a flower, plays a crucial role in seed formation by receiving pollen during fertilization.

This process initiates the development of seeds from the fertilized ovules. The stigma's ability to capture and facilitate pollen is essential for sexual reproduction in flowering plants.
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.
In the context of a flower, "sigma" likely refers to the stigma, which is the part of the pistil that receives pollen during the pollination process. The stigma is typically sticky or feathery, allowing it to effectively capture pollen grains brought by wind or pollinators. Once pollen lands on the stigma, it germinates and grows a pollen tube down into the ovary, facilitating fertilization. This process is crucial for the reproduction and development of seeds in flowering plants.
Pollen grains land on the stigma of the flower, which is the sticky structure at the top of the pistil. Once the pollen grains land on the stigma, they can germinate and grow a pollen tube through the style to reach the ovules in the ovary for fertilization to occur.
The pollen tube serves as a bridge between the pollen grain and the egg in flowering plants. Once the pollen grain lands on the stigma, it germinates and forms a pollen tube that grows down through the style towards the ovary, where it delivers the male gametes to the egg for fertilization.
During pollination, pollen grains attach to the stigma, which is the upper part of the pistil in flowering plants. The stigma is often sticky, allowing it to capture and hold pollen from visiting pollinators or the wind. Once the pollen adheres to the stigma, it can germinate and grow a pollen tube down the style towards the ovary, facilitating fertilization.
