How does the pollen grains tube reach the ovary?
Pollen tubes are extensions of pollen grains that grow and elongate to penetrate the ovary. They are guided by chemical signals released by the ovary, which direct the path of the pollen tube towards the ovule where fertilization can occur.
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
How does the pollen tube grow through the style?
The pollen tube grows through the style by elongating and penetrating the tissues. It is guided by chemical signals and nutrients in the style, which help direct its growth towards the ovary. This process is crucial for successful fertilization in plants.
After the pollen grains land on the stigma what begins to grow from a cell in the pollen?
A pollen tube grows from a cell in the pollen and penetrates the style of the flower, allowing the sperm cells to travel to the ovule. This process is essential for fertilization to occur in plants.
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 does a pollen grain landing near an ovule produce?
If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.
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 are the examples of chemotropism?
Examples of chemotropism include pollen tube growth towards ovules in plants, fungal hyphae growth towards nutrients in the soil, and bacterial movement towards sources of nutrients or away from harmful substances.
How does a pollen tube form?
A pollen tube forms when a pollen grain lands on the stigma of a flower and germinates. The pollen grain absorbs water and begins to grow a tube that will penetrate the style of the flower and reach the ovary. This is a crucial step in the process of fertilization in plants.
What stimulates to pollen tube to grow?
Lipid that is found on the surface of the stigma stimulates the growth of the pollen tube, which enters through the style to the ovary. Hope that helps

What serves as a bridge between the pollen grain and the egg?
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.
