The pollen tube serves as a conduit for sperm cells to travel from the pollen grain to the ovule for fertilization in seeded plants. It extends down the style of the pistil to reach the ovule and deliver the sperm cells. Once the sperm cells reach the ovule, they fertilize the egg cell, leading to seed formation.

What does the stem do on a plant?
The stem of a plant serves as a support structure, holding up the plant and its leaves, flowers, and fruits towards the sunlight. It also transports water and nutrients from the roots to the rest of the plant and helps in the process of photosynthesis.
What is the scientific name for a purple tube sponge?
The scientific name of the purple tube sponge is Aplysina lacunosa.
Which of these is classified in the phylum Echinodermata animals with a spiny exterior and tube feet?
Sea urchins, sand dollars, and sea stars are classified in the phylum Echinodermata. They have a spiny exterior and tube feet that they use for movement and feeding.
What is a blackfish carpenter bee-sized fly with a large mouth tube?
ANSWER It is probally a bee fly
What is a tubeworms phylum?
Tubeworms belong to the phylum Annelida, which includes segmented worms. They are specifically classified in the class Polychaeta, which comprises marine worms known for their tube-dwelling lifestyle.
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.
Where does fertilisation take place in a plant?
pollen tube
What structure transports sperm in the ovule in flowering plants?
The pollen tube is a structure designed to help a particle of pollen, the male side of the plant fertilization process, to access the egg cell in the female part of the plant. The egg cells are typically protected by cell walls and shells designed to keep them in place and protect them from outside elements. Pollen particles create pollen tubes to reach through these walls and access the egg cell.
How do flowers help a plant?
Flowers aid a plant in reproducing. Bees come and get pollen from a flower, and in the prosess take pollen from the male part of a flower and it is then placed on the female part. The pollen then produces a pollen tube and will soon become fruit or seeds.
Is the stamen in the male organ or the female organ in the plant?
The Stamen is the male organ in a plant. It gives off pollen. The pistil is the female organ. The pollen lands in the flower. The pollen then produces a tube that goes to the ovary and fertilizes the seed.
During sexual reproduction in a flowering plant a pollen tube goes down through the?
Style.
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 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.
Are all pollen tube of equal length?
No, not all pollen tubes are of equal length. The length of a pollen tube can vary depending on several factors, including the species of the plant, environmental conditions, and the compatibility of the pollen with the ovule. Additionally, the growth rate of the pollen tube can be influenced by the availability of nutrients and water in the surrounding tissue. Thus, while some pollen tubes may be similar in length, there is considerable variation among them.
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 role do the pollen tube play in fertilization?
Pollen tubes transport the male gametes (sperm cells) from the pollen grain to the ovule for fertilization. The pollen tube delivers the sperm cells to the female reproductive structure, allowing the male gametes to reach the egg cell and fertilize it.
During sexual reproduction in a flowering plant a pollen tube grows down through the?
During sexual reproduction in a flowering plant, a pollen tube grows down through the style to reach the ovary. This enables the male gametes (sperm cells) to reach the female gamete (egg cell) for fertilization to occur.
