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.
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.
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.
Does a egg if a plant pass through the pollen tube or something different?
An egg in a plant does not pass through a pollen tube. In plant reproduction, the egg cell is located in the ovule within the ovary of the flower. The pollen tube allows the sperm cells to travel from the pollen to the egg for fertilization to occur.
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 stimulate the 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

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.

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).
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

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.
