they germinate and grow a small tube all the way to the ovary

When a flower is pollinated, the pollen grain lands on the stigma of the flower, which is the female reproductive organ. The pollen grain then germinates, forming a pollen tube that grows down through the style to reach the ovary where fertilization can occur.
The pollen grain needs to land on the stigma of the plant for successful pollination to occur.
When a flower is pollinated, a grain of pollen falls on the stigma, which is the tip of the female reproductive structure called the pistil.

when pollen grain are transferred from the stigma the ovule of the flower , whats takes place
When a flower is pollinated, the pollen grain lands on the stigma of the flower, which is the female reproductive organ. The pollen grain then germinates, forming a pollen tube that grows down through the style to reach the ovary where fertilization can occur.
The pollen grain needs to land on the stigma of the plant for successful pollination to occur.
The stigma recieves the pollen grain from the anther. It then travels down the pollen tube inside the style and goes to the ovary.
When a flower is pollinated, a grain of pollen falls on the stigma, which is the tip of the female reproductive structure called the pistil.
In a flower carpel, the stigma is the terminal portion that has no epidermis and is fitted to receive pollen.
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.
The sticky bulb called the stigma. A part of the female aspect of the flower.
A pollen tube forms when a pollen grain lands on the stigma of a flower and germinates. The pollen grain absorbs water and begins to grow a tube that will penetrate the style of the flower and reach the ovary. This is a crucial step in the process of fertilization in plants.
In order for pollination to occur, what must happen to the pollen grains is that they have to be transferred to the stigma in a flower of the same species. The stigma is the female part of the flower.
