What else can I help you with?
What happens to pollen grains immediately after pollination?
Pollen germination starts on compatible stigma
What happens once the pollen lands on the stigma?
Pollination
Where do pollen grains land on the pistil?
the style
What part of the plant receive pollen?
stigma
In what structure do the pollen grains come in contact with the ovule?
Pollen grains come in contact with the ovule through the stigma, which is the receptive tip of the female reproductive organ (pistil) in a flower. Pollen grains germinate on the stigma, form a pollen tube, and then grow down to the ovule for fertilization.
What happens when pollen is moved from the anthers to the stigma?
Pollen grains contain the male gamete (sex cell).
Where in the flower do pollen grains land in order to begin the process of fertilization?
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.
What is the job for stigma?
It allows landing of pollen grains and germination of compatible pollen grains only.
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.
Why is a flower's stigma sticky?
The stigma of a flower is sticky to help trap and hold onto pollen grains. This stickiness allows the pollen to adhere to the stigma and then germinate, helping with the process of fertilization.
What happens when pollen grains land on the stigma of a flower of a different kind?
It depends. If the pollen that the plat came from is part of the other plant's family, then it is crossbred. However, if not, the pollen will not travel down through the other plant's stigma. Such as a white and red rose will make either a pink or a red rose.
Which structure is where pollen grains land and stick?
The structure where pollen grains land and stick is the stigma of a flower. The stigma is the uppermost part of the pistil, and its sticky surface helps to capture and hold pollen grains for fertilization.
