how does the male gamete in flowers differ to the animal male gamete?
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.
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 is the long extension of the ovary called of the flower?
The long extension of the ovary in a flower is called the "style." The style connects the ovary, which contains the ovules, to the stigma, where pollen is received. It plays a crucial role in the fertilization process by allowing pollen tubes to grow from the stigma down through the style to reach the ovary.
Do all pollen tubes reach the ovule?
No, not all pollen tubes reach the ovule. After pollination, multiple pollen tubes may grow down the style, but typically only one successfully penetrates the ovule to deliver sperm cells for fertilization. The competition among pollen tubes ensures that the most viable one reaches the ovule, while others may abort or be blocked along the way.
Where is the style on a hibiscus plant?
The style on a hibiscus plant is located within the flower. It is the elongated part of the carpel that connects the stigma, where pollen lands, to the ovary, which contains the ovules. The style plays a crucial role in the reproductive process by allowing pollen tubes to grow down to the ovary for fertilization.

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 is the function of the style in the flower?
The style in a flower is part of the female reproductive structure that connects the ovary to the stigma, allowing pollen to reach the ovules for fertilization. It plays a crucial role in the pollination process by providing a pathway for pollen tubes to grow and facilitate fertilization.

What is the functionof the tubes that grow from pollen grains?
They provide a pathway for the male gamete to travel down through the style. This is necessary for the gamete to reach the female cell (ovule) in the ovary for fertilization to take place.

The style on a hibiscus plant is located within the flower. It is the elongated part of the carpel that connects the stigma, where pollen lands, to the ovary, which contains the ovules. The style plays a crucial role in the reproductive process by allowing pollen tubes to grow down to the ovary for fertilization.
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.
What stimulates the pollen 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 is the function of the pollen tube?
The pollen tube of most seed plants acts as a conduit to transport sperm cells from the pollen grain, either from the stigma (in flowering plants or angiosperms) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms (conifers and gnetophytes).
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 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
