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.
How the nucleus from a pollen grain fertilize a female egg cell
How the nucleus from 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.
The pollen tube carries the male gametes (sperm) from the pollen grain to the egg cell in the ovule. Once the pollen tube reaches the ovule, the sperm fertilizes the egg cell, resulting in the formation of a seed.
The combination of material from a pollen grain with an egg to form a seed is what bees carry from one plant to another, unknowingly. When the bee lands on a plant it picks up pollen and carries this to another plant.

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

a pollen grain
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.
