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.
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 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.

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 stimulates to pollen tube to grow?

What stimulate the pollen tube to grow?

What are the steps of pollination to the point that the seed is formed?
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA
Grows from the pollen grain to the ovule?
Pollen tubes grow from the pollen grains to the ovules. Lipids on the surface of the stigma stimulate growth of the pollen tubes. Self sterile plants prevent themselves from growing seeds by not creating these lipids.
What happens from the time pollen lands on the female part of the flower until the seed forms?
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA
