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.
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.

What moves down the pollen tube into the ovary?
Pollen
What grows out of the pollen grain and into the stigma then carries the pollen nucleus down to the egg?
The structure that grows out of the pollen grain and into the stigma is called the pollen tube. Once the pollen grain lands on a compatible stigma, it germinates and forms this tube, which extends down through the style to reach the ovule in the ovary. The pollen tube carries the male gamete (pollen nucleus) to the egg cell for fertilization. This process is essential for sexual reproduction in flowering plants.
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
After pollen grows a tube down the style?
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 is a pollen tube?
A pollen tube is a structure that develops from a pollen grain after it lands on the stigma of a flower. It grows down through the style of the flower to reach the ovary where it delivers the male gametes for fertilization to occur. This process is essential for plant reproduction.
What structure are you likely able to see in the pollen tube and when would you be able to see it?
You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
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.
