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.


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 is the fate of the tube nucleus in the pollen tube?

The tube nucleus in the pollen tube typically disintegrates as it moves downwards in the pollen tube to ensure that the sperm cells reach the ovule without interference. This allows for successful fertilization to occur by facilitating the fusion of the sperm cells with the egg cell and central cell in the ovule.


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.


In what structure do the pollen grains come in contact with the ovule?

Pollen grains come in contact with the ovule through the stigma, which is the receptive tip of the female reproductive organ (pistil) in a flower. Pollen grains germinate on the stigma, form a pollen tube, and then grow down to the ovule for fertilization.

When a pollen grain joins with an ovam what is called?

Fertilization resulting in the formation of a zygote or embryo; technically, the pollen grain does not join with the ovule. A pollen tube grows from the pollen grain - this contains the gamete which fuses with the ovule.


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 does a pollen grain landing near an ovule produce?

If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.


The pollen tube fertilizes the?

ovule


What happens once pollen is transferred?

Once pollen is transferred, it can fertilize the ovule to form a seed. This process initiates the development of new plants. The pollen tube grows towards the ovule, delivering sperm cells for fertilization.


In ovule formation what happens when the pollen tube does not pass through the micropyle?

If the pollen tube does not pass through the micropyle during ovule formation, fertilization cannot occur because the sperm cells contained within the pollen tube will not reach the egg cell. This will prevent the fusion of gametes and subsequently the development of seeds.


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 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.


Describe how a pollen tube carries speem to the ovule inaflower?

In flowering plants, after pollination, a pollen grain germinates on the stigma, forming a pollen tube. This tube grows down through the style toward the ovule, guided by chemical signals. As the pollen tube extends, it transports sperm cells from the pollen grain to the ovule, where fertilization occurs, leading to the development of seeds. The successful delivery of sperm to the ovule is crucial for reproduction in flowering plants.


What does a pollen grain landing near a ovule produce?

It produces a pollen tube .


Where the pollen tube grow to or through?

The pollen tube grows out of or through the pollen grain.


What is pollen tube germination?

Pollen tube germination is the process by which a pollen grain, upon landing on a compatible stigma, develops a tube that extends down the style toward the ovule in the ovary. This tube carries sperm cells from the pollen grain to fertilize the ovule, leading to seed formation. The germination process involves the hydration of the pollen grain and the growth of the tube, which is guided by chemical signals from the ovule. Successful germination is crucial for plant reproduction.
