Stamen
The sticky bulb called the stigma. A part of the female aspect of the flower.
This tiny grain is called pollen grain.
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.
No, after a research it is not seen that a pollen grain of a flower have only one lobe. Commonly pollen grain have two or three lobes.
Pollen grain
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.

pollen grains are little grains in side a flower
When a pollen grain reaches the stigma of another flower of the same species, the process that follows is called pollination. The pollen grain germinates on the stigma, forming a pollen tube that extends down the style toward the ovary. This tube transports sperm cells to the ovule, leading to fertilization and the formation of seeds.
The structure grown by a pollen grain that contains two sperm nuclei is called the pollen tube. The pollen tube is responsible for delivering the sperm nuclei to the ovule for fertilization in plants.
