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.

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.
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.
How does fertilization take place in flowers?
the pollen grain lands ot the tip of pistle called as stigma and then pollen tube from pollen grain germinates and it reaches the ovary through style(containing 2 male gamets).. then fertilisation takes place... or is when the male sex cells inside the pollen grains fuses with the female sex cells inside to produce a seed embryo Pollination transfers the pollen grain to the stigma. However, for hertilisation to take place, the nucleus of the pollen grain must fuse with the nucleus of the ovum, which is inside an ovule in the ovary. To transfer the nucleus to the ovum, the pollen grain grows a tube, which digest its way through the tissue of the style and into the ovary. Here it grows around the opening in an ovule. The tip of the tube dissolves and allows the pollen grain nucleus to move out of the tube and into the ovule. Here it fertilises the ovum (egg cell) nucleus.
