when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with 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.
To fertilize an egg, a pollen grain first lands on the stigma of a flower. From there, it germinates and forms a pollen tube that grows down through the style and into the ovary. The pollen tube navigates to the ovule, where it releases sperm cells. One sperm cell then fertilizes the egg, resulting in the formation of a zygote.
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.

The pollen tube serves as a bridge between the pollen grain and the egg in flowering plants. Once the pollen grain lands on the stigma, it germinates and forms a pollen tube that grows down through the style towards the ovary, where it delivers the male gametes to the egg for fertilization.
no the pollen grain contains the male genetic material - sperm cells

fertilization
No, pollen grain does not contain the egg of the plant. It contains the male gamete of the plant.Egg of the plant is present in the ovaries.
pollen tube
A polln grain after germination sends a pollen tube in the ovule to release male gametes near the egg cell or ovum.
