When a pollen grain germinates on the stigma, it forms a structure called the pollen tube. This tube grows down through the style towards the ovary, allowing sperm cells to travel to the ovule for fertilization. The successful formation of the pollen tube is crucial for the fertilization of the egg cell and subsequent seed development.
What else can I help you with?
When a pollen grain reaches the stigma of another flower of a plant of the same species what happens next is called?
When a pollen grain reaches the stigma of another flower of the same species, the process that follows is called pollination. The pollen grain germinates on the stigma, forming a pollen tube that extends down the style toward the ovary. This tube transports sperm cells to the ovule, leading to fertilization and the formation of seeds.
What is the transfer of pollen to stigma called?
The transfer of pollen to the stigma of a flower is called pollination. The transfer of pollen is called pollenation.
What grows out of the pollen grain and into the stigma then carries the pollen nucleus down to the egg?
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.
What receives the pollen during fertilization?
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.
When a flower is pollinated the grain of pollen falls were?
When a flower is pollinated, the pollen grain lands on the stigma of the flower, which is the female reproductive organ. The pollen grain then germinates, forming a pollen tube that grows down through the style to reach the ovary where fertilization can occur.
Stigma?
The part of the pistil where pollen germinates.
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 does the stigma do to make a seed?
The stigma, part of the female reproductive structure of a flower, plays a crucial role in seed formation by receiving pollen during fertilization. Once pollen lands on the stigma, it germinates and forms a pollen tube that travels down to the ovary, where fertilization occurs. 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.
What part of the flower does pollen travel through?
Pollen travels through the style, which is the elongated part of the pistil located between the stigma and the ovary. When pollen lands on the stigma, it germinates and forms a pollen tube that grows through the style to reach the ovary, where fertilization occurs. This process is essential for the reproduction of flowering plants.
The part of a flower pollen sticks to?
That is called the stigma.
What is the tube in the stigma called?
The tube in the stigma is called the style. It serves as the bridge between the stigma and the ovary, allowing for the transfer of pollen for fertilization.
What takes place when pollen lands on the stigma?
When pollen lands on the stigma of a flower, it germinates and grows a pollen tube through the style to reach the ovary. This process allows for fertilization to occur, where the sperm travels down the pollen tube to fertilize the egg cell in the ovule. This ultimately leads to the formation of seeds within the ovary.
