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 is it called when the pollen has gone down the pollen tube and enters the ovary?
When the pollen has traveled down the pollen tube and enters the ovary, it is called fertilization. This is the process where the male gamete in the pollen combines with the female gamete in the ovule to form a zygote, which will develop into a seed.
What is the tube that grows out of a pollen grain contains?
The tube that grows out of a pollen grain contains two sperm cells. These sperm cells are needed for fertilization in plants, where one sperm cell fuses with the egg cell to form a zygote, while the other fuses with the central cell to form the endosperm.
How does the pollen go through the style?
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.
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.

Inside what structure do the sperm of seed plants form?
The sperm of seed plants form inside the pollen tube, a structure that develops from the pollen grain. The pollen tube grows towards the ovule to deliver the sperm cells for fertilization.

When the pollen has traveled down the pollen tube and enters the ovary, it is called fertilization. This is the process where the male gamete in the pollen combines with the female gamete in the ovule to form a zygote, which will develop into a seed.
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.
How does the pollen tube nucleus function in fertilization?
The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary

How pollen tube grows down the style?
how pollen tube grows down through the style
What is the function of a pollen tube?
The long tube
What moves down the pollen tube into the ovary?
Pollen
A pollen grain forms a tube leading to the flower's what?
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 part of the flower is the pollen kept?
The pollen is made and stored by the anthers.In flowering plants the vegetative tube cell produces the pollen tube.
