Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.
What else can I help you with?
What is the process where a plant sperm fertilizes a plant egg?
cross pollination
What happens between pollination and fertilisation?
After pollination, the pollen grain germinates and forms a pollen tube that grows down the style of the pistil to reach the ovule. Fertilisation occurs when the sperm cell from the pollen grain fuses with the egg cell in the ovule, resulting in the formation of a zygote.
What fertilizes the eggs in pea plants?
In pea plants, the eggs are fertilized by pollen. Pollen contains the male gametes (sperm cells) that fertilize the female gametes (egg cells) in the ovule of the flower. This process leads to seed development in pea plants.
What is the fusion of pollen and ovule called?
The fusion of pollen and ovule is called fertilization. This process involves the union of the sperm cell from the pollen with the egg cell in the ovule, resulting in the formation of a zygote, which eventually develops into a seed.
How do the sperm nuclei in a pollen grain reach the egg nucleus in an ovule?
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.
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 the pollen grain that sends tube down pistil and unites with the ovule?
The pollen grain that sends a tube down the pistil and unites with the ovule is called a sperm cell. This process is known as fertilization and it leads to the formation of a seed. The sperm cell from the pollen grain fertilizes the egg cell within the ovule, initiating seed development.
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.
Where do the pollen grains go after pollination?
After pollination, the pollen grains germinate on the stigma and grow a pollen tube down the style to reach the ovule. The pollen tube delivers sperm cells to fertilize the egg cell within the ovule, leading to the formation of a seed.
What is the role of pollen tube in seeded plant?
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.
Where does sexual reproduction occur?
Overall- Pollination; pollen carried from anther to stigma; sperm nuclei germinates out of pollen grain, goes down style into ovule and fertilizes egg nuclei (double fertilization occurs), Seed develops from ovule and fruit develops from ovary. Next seed is dispersed.
Where does sexual reproduction occur in?
Overall- Pollination; pollen carried from anther to stigma; sperm nuclei germinates out of pollen grain, goes down style into ovule and fertilizes egg nuclei (double fertilization occurs), Seed develops from ovule and fruit develops from ovary. Next seed is dispersed.
What name is used when the pollen joins the ovule?
Fertilization occurs when pollen joins with the ovule, resulting in the formation of a fertilized egg or zygote.
