After pollen grows a tube down the style?
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
How the nucleus form a pollen grain fertilize a female egg cell?
During pollination, the male nucleus in a pollen grain is transferred to the female egg cell within the ovule of a plant. This transfer is facilitated by a pollen tube that grows from the pollen grain to the ovule. Once the pollen tube reaches the egg cell, the male nucleus fuses with the female nucleus to form a zygote, which eventually develops into a new plant embryo.
What is the transer of pollen grains to ovules?
It contains a tiny egg nucleus which will fuse with nucleus of the male cell.

How many chromosomes are there in the female nucleus of a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.

Once the pollen tube reaches the egg cell, the male nucleus fuses with the female nucleus to form a zygote, which eventually develops into a new plant embryo.
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 is the transer of pollen grains to ovules?
It contains a tiny egg nucleus which will fuse with nucleus of the male cell.
What grows out of the pollen grain and into the stigma then carries the pollen nucleus down to the egg?
The structure that grows out of the pollen grain and into the stigma is called the pollen tube. Once the pollen grain lands on a compatible stigma, it germinates and forms this tube, which extends down through the style to reach the ovule in the ovary. The pollen tube carries the male gamete (pollen nucleus) to the egg cell for fertilization. This process is essential for sexual reproduction in flowering plants.
What is the function of tube nucleus?
The tube nucleus is a specialized structure found in the pollen grain of flowering plants. Its primary function is to guide the growth of the pollen tube during fertilization. Once the pollen grain lands on a compatible stigma, the tube nucleus directs the formation of the pollen tube, allowing sperm cells to travel to the ovule for fertilization. This process is crucial for the successful reproduction of flowering plants.
