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.
What else can I help you with?
Where do pollen grains attach during pollination?
During pollination, pollen grains attach primarily to the stigma, which is the receptive part of a flower's female reproductive organ (the pistil). The stigma is often sticky or has specialized structures that facilitate the adhesion of pollen. Once attached, pollen grains germinate and grow a pollen tube down the style to reach the ovary, where fertilization occurs. This process is crucial for the reproduction of flowering plants.
Does pollen tube grow before or after pollination occurs?
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.
What happens once the pollen lands on the stigma?
Pollination
What part of the plant receive pollen?
stigma
What transfer of pollen from an anther to a stigma?
yes, but it is the anther to the stigma of a different plant self pollination is the transfer of pollen from the anther to the stigma of the same plant
Which structure do pollen grains attach during 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.

What is the pollen transferred from the stamen to the stigma?
pollination-it's that simple :)
The transfer of pollen from a male structure to a female structure?
This process is called pollination, which involves the movement of pollen grains from the anther (the male structure) to the stigma (the female structure) of a flower. Once pollination occurs, fertilization can take place, leading to the development of seeds and fruit.
What is the process of transferring pollen from the reproductive structure to a female reproductive structure?
The process of pollination.
Pollen grains move from a flower's stamen to it's pistil during what?
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
Is the process of transferring pollen from a male reproductive structure to a female reproductive structure?
The process of pollination.
Are pollen grains formed within the stigma?
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.
Does pollen tube grow before or after pollination occurs?
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.
What structure are you likely able to see in the pollen tube and when would you be able to see it?
You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
What happens once the pollen lands on the stigma?
Pollination
What is the transfer of pollen from the anther to the stigma called?
The transfer of pollen from the anther to the stigma is called pollination. This process is essential for fertilization and the production of seeds in plants. Pollination can occur through various means, such as wind, insects, birds, or other animals.
