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.
What travels down the pollen tube and fertilizes?
The pollen tube carries the male gametes (sperm) from the pollen grain to the egg cell in the ovule. Once the pollen tube reaches the ovule, the sperm fertilizes the egg cell, resulting in the formation of a seed.
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.
After pollenation each pollen grain grows a?
After pollination, each pollen grain grows a pollen tube that extends down into the style of the flower and reaches the ovary. The pollen tube delivers the male gametes (sperm cells) to the ovule for fertilization to occur.
What is the combination of material from a pollen grain with an egg to form a seed?
The combination of material from a pollen grain with an egg to form a seed is what bees carry from one plant to another, unknowingly. When the bee lands on a plant it picks up pollen and carries this to another plant.
What grows from the pollen grain go the ovule?
The pollen grain produces a pollen tube that grows towards the ovule in order to deliver the male gametes for fertilization. Once the pollen tube reaches the ovule, the male gametes are released to fertilize the female gametes inside the ovule, leading to the formation of seeds.
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.
What travels down the pollen tube to fertilize the pistil?
The male gametes (sperm cells) travel down the pollen tube to fertilize the female gametes (egg cells) located in the pistil. This process is essential for sexual reproduction in plants.
What forms when stigma and pollen develop?
When stigma and pollen develop, they enable the process of pollination to occur. The stigma is the part of the pistil that receives the pollen, while the pollen contains the male gametes needed for fertilization. Once the pollen lands on the stigma, it can germinate and grow a pollen tube to transport the male gametes to the ovule for fertilization.
What travels down the pollen tube and fertilizes?
The pollen tube carries the male gametes (sperm) from the pollen grain to the egg cell in the ovule. Once the pollen tube reaches the ovule, the sperm fertilizes the egg cell, resulting in the formation of a seed.

After pollination, each pollen grain grows a pollen tube that extends down into the style of the flower and reaches the ovary. The pollen tube delivers the male gametes (sperm cells) to the ovule for fertilization to occur.
When a pollen grain joins an ovum?
A polln grain after germination sends a pollen tube in the ovule to release male gametes near the egg cell or ovum.
What serves as a bridge between the pollen grain and the egg?
The pollen tube serves as a bridge between the pollen grain and the egg in flowering plants. Once the pollen grain lands on the stigma, it germinates and forms a pollen tube that grows down through the style towards the ovary, where it delivers the male gametes to the egg for fertilization.
What occurs between pollination and fertilization?
After pollination, the pollen grain germinates on the stigma and grows a pollen tube down to the ovary. Fertilization occurs when the male gametes in the pollen tube combine with the female gametes in the ovule, forming a zygote.
What is responsible for reproduction?
reproduction are of 2 types sexual reproduction which involves gametes male gametes:-- sperms female gametes:-- ovum these 2 gametes need to be fused together to form an embryo then through mitosis it will divide millions of time to make a baby in plants male gametes:-- pollen grain female gametes:-- ovary in these when pollen gets in another flower due to pollination it forms an pollen tube through the style and fuses with the ovary and forms seeds!! in short the gametes are responsible for reproduction in sexual reproduction
Where does the pollen tube go?
It goes in the stigma, which is what catches the flying pollen in the air, and it's also the sticky regimen.
