What else can I help you with?
What is the sticky or hairy stalk that captures pollen grains?
The sticky or hairy stalk that captures pollen grains is called the stigma. This structure is part of the female reproductive organ of a flower and plays a key role in the pollination process by trapping pollen grains that land on it.
Does pollination occurs when pollen grains land on the sticky surface of the anther?
No, pollination occurs when pollen grains land on the sticky surface of the stigma.
What pollen grains land on a female reproductive structure?
Pollen grains from the male reproductive structures of flowering plants (stamens) land on the female reproductive structure (pistil) during the process of pollination. The pollen typically comes from the same species, as this ensures compatibility for fertilization. When the pollen grain adheres to the stigma of the pistil, it germinates and grows a pollen tube down to the ovary, allowing sperm cells to reach and fertilize the ovules. This process is crucial for the production of seeds and fruit.
How does pollen grain reaches the ovary?
When pollen grains land on the stigma(funny stick thingo on a flower), it wil start to grow a pollen tube, towards the ovary and the ovules. Then it GOES THROUGH the tube and =============*FERTILISATION*=====================
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.
WHY IS STIGMA IS STICKY?
So the pollen will stick.
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.
Where do pollen grains land on the pistil?
the style

Does pollination occurs when pollen grains land on the sticky surface of the anther?
No, pollination occurs when pollen grains land on the sticky surface of the stigma.
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.
The part of the pistil where pollen grains land is the?
The stigma

Where do pollen grains go?
Out of hundreds and thousands of pollen grains produced by each flower a few land on the stigma during pollination and others just wither away.
What help the pollen grains to stay on the tip of the style after they land there?
sticky stigma
What is anther pollen?
Anther pollen refers to the pollen grains produced by the anther, which is the male reproductive organ of a flower. These pollen grains contain the male gametes needed for fertilization when they land on the stigma of a flower.
