As pollen travels down the style, it forms a pollen tube, which carries sperm cells toward the ovule in the ovary. The tube grows through the tissue of the style, guided by chemical signals, until it reaches the ovule. Once it arrives, one sperm cell fertilizes the egg cell, while the other typically fuses with two polar nuclei to form the triploid endosperm, which will nourish the developing embryo. This process is essential for seed development in flowering plants.

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 does pollen travel down?
Pollen travels down the style, which is the elongated part of the pistil in a flower. When a pollen grain lands on the stigma, it germinates and forms a pollen tube that grows through the style toward the ovary, where fertilization occurs. This process is essential for the reproduction of flowering plants.
What is the part that carries the pollen to the ovary?
The part that carries pollen to the ovary is called the style. It is a slender stalk that connects the stigma, where pollen is received, to the ovary, which contains the ovules. The pollen travels down the style through a structure called the pollen tube, allowing fertilization to occur.
Where does pollen enter the female part of a plant?
Pollen enters the female part of a plant through the stigma, which is the sticky, receptive surface located at the top of the pistil. From the stigma, the pollen travels down the style to reach the ovary, where fertilization takes place.
What receives the pollen during fertilization?
During fertilization in flowering plants, the stigma of the pistil receives the pollen. The stigma is the sticky top part of the pistil, which captures and holds the pollen grains. Once the pollen lands on the stigma, it germinates and forms a pollen tube that travels down the style to reach the ovary, where fertilization occurs.
What is the purpose of the style?
it is the tube that the pollen travels down to the ovarys
After pollen grows a tube down the style?

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 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.
Which part of a flower receives pollen during pollination?
stigma True, but Ill explain more... Pollen from the Stamen- (male reproductive parts of a flower) must land on the Pistil-(female reproductive parts of a flower) for fertilization to occur, and thats when the seed grows in the ovary. :)
Which part of the plant is directly involved sexual reproduction?
The flower of the plant is directly involved in sexual reproduction.More specifically, the anthers produce pollen. The pollen then lands on another plant's stigma and travels down the style, and fertilizes the ovules.
