Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
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.
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.
What do we call the joining of the pollen grain with the ovule?
Pollination.
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 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 does a pollen grain landing near a ovule produce?
It produces a pollen tube .
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 joining of the nuclei from a pollen grain to those of an ovule called?
Fertilization
The structure that grows from a pollen grain to an ovule and enables a sperm to pass directly to an egg?
pollen tube
What does a pollen grain and ovule each contain?
Pollen grains contain the male gametes required for sexual reproduction of a plant/ flower. These are haploid, and only contain half the full set of chromosomes; the other half is contributed by the female gamete (or ovule).A grain of pollen contains:a larger vegetative cell (also called the tube cell) inside of which is aa smaller germ cell (also called the generative cell).The pollen grain "germinates" on the stigma of the receptive flower and grows down the style, once it reaches the ovule the germ cell/ nucleus fuses with the nucleus of the ovule and an embryo is formed
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.
