Pollen grains are transferred to the stigma of a flower, where they germinate and form a pollen tube. This tube grows down through the style, which is the elongated part of the pistil, toward the ovary. As the pollen tube moves through the style, it carries sperm cells that will eventually fertilize the ovules in the ovary. This process is crucial for the reproduction of flowering plants.
What else can I help you with?
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
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.
What is the part of the flower that carries the pollen to the ovary?
The part of the flower that carries pollen to the ovary is called the style. The style is a slender stalk that connects the stigma, where pollen is received, to the ovary, which contains the ovules. When pollen grains germinate on the stigma, they grow a pollen tube through the style to facilitate the transfer of sperm cells to the ovary for fertilization.
What is the part that carries the pollen to the ovary?
The part that carries pollen to the ovary is called the style. It is a slender stalk that connects the stigma, where pollen is received, to the ovary, which contains the ovules. The pollen travels down the style through a structure called the pollen tube, allowing fertilization to occur.
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.

How pollen tube grows down through the style?
The pollen tube elongates down the style through a process called tip growth, where the cell tip extends and pushes through the tissue. This growth is facilitated by the interaction of enzymes and proteins at the cell wall to create a pathway for the pollen tube to follow. The pollen tube is guided by chemical signals and physical cues in the style to reach the ovary for fertilization.
Function of a style?

Style.
What is the structure that allows sperm cells to move through the style of a flower?
The structure that allows sperm cells to move through the style of a flower is the pollen tube. Pollen tubes carry the sperm cells from the pollen grains on the stigma, through the style, and into the ovary where fertilization can occur. This process is crucial for sexual reproduction in plants.
