Ungerminated pollen grain is inactive and has not started the process of fertilization, while germinated pollen grain has started growing a pollen tube towards the ovule for fertilization. Germinated pollen grain is actively involved in the fertilization process, while ungerminated pollen grain is not.
This tiny grain is called pollen grain.
If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.
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.
Fertilization resulting in the formation of a zygote or embryo; technically, the pollen grain does not join with the ovule. A pollen tube grows from the pollen grain - this contains the gamete which fuses with the ovule.

yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores
This tiny grain is called pollen grain.
No, sperm cells do not grow out of a pollen grain. In plants, sperm cells are produced within the pollen grain, and they are involved in fertilization when the pollen grain reaches a female reproductive structure. Each pollen grain contains two sperm cells.
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.

the pollen grain
The pollen grain produces a narrow tube called the corbicula.
no the pollen grain contains the male genetic material - sperm cells
The male sex cells from pollen grain are called male gametes.
