Pollen travels down the style, which is the elongated part of the pistil in a flower. When a pollen grain lands on the stigma, it germinates and forms a pollen tube that grows through the style toward the ovary, where fertilization occurs. This process is essential for the reproduction of flowering plants.
What else can I help you with?
How pollen tube form?
Pollen tube formation begins when a pollen grain lands on a compatible stigma, where it absorbs moisture and germinates. The pollen grain then produces a pollen tube that grows down the style towards the ovule, facilitated by the tube cell and generative cell within the pollen grain. The pollen tube penetrates the ovule through the micropyle, allowing the sperm cells to travel down the tube to fertilize the egg cell. This process is crucial for successful fertilization and seed development in flowering plants.
Where does grass pollen go when it gets to the other flower?
When grass pollen reaches another flower, it typically lands on the stigma, the receptive part of the female reproductive structure. If the pollen matches the flower's compatibility requirements, it germinates and forms a pollen tube that extends down into the ovary. This allows sperm cells carried by the pollen to travel down the tube and fertilize the ovules, leading to seed development. Thus, the pollen plays a crucial role in the reproduction process of flowering plants.
After pollen grows a tube down the style?
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
What does pollen from the stamen reach?
Pollen from the stamen reaches the stigma of a flower, which is part of the pistil. This transfer is crucial for the process of fertilization, as it allows the sperm cells contained within the pollen to travel down the style to the ovary, where they can fertilize the ovules. This process is essential for the production of seeds and the continuation of plant species.
When the pollen grain germinates on the stigma what burrow is it called?
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 travels down the pollen tube to fertilize the pistil?
The male gametes (sperm cells) travel down the pollen tube to fertilize the female gametes (egg cells) located in the pistil. This process is essential for sexual reproduction in plants.

What structure will pass down the pollen tube?
the pollen grain
What transfer pollen from stamen to ovules?
A pollen tube grows from the pollen grain down through the style. The pollen tube enters the ovary and reaches an olvule. The sperm then travels down the pollen tube and fertilizes the egg in the ovule. So a pollen tube.

Can pollen travel up to 2 km?
yes
