What is difference between ungerminated pollen grain and germinated pollen grain?
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.
What makes seeds when combined with a flower's eggs?
This tiny grain is called pollen grain.
What does a pollen grain landing near an ovule produce?
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.
How close to the egg can the pollen grain get?
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.
When a pollen grain joins with an ovam what is called?
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.
Do Dicot have pollen grain?
yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores

Does sperm cell grows out of a 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.
Can a pollen grain of a flower have one lobe?
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.
How does a pollen grain travel through the parts of a flower to finally become a seed?
The pollen grain released from the anther lobe during anthesis reaches the stigma by pollination. Thereafter, it germinates on the compatible stigma to send pollen tube to the micropyle of the ovule inside the ovary. The male gametes from the pollen grain are transferred to the embryo sac for fertilization and the ovule is converted into a seed when zygote develops into an embryo.

What structure will pass down the pollen tube?
the pollen grain
Does the pollen grain contain the egg of an angiosperm?
no the pollen grain contains the male genetic material - sperm cells
A pollen grain produce a narrow tube called?
The pollen grain produces a narrow tube called the corbicula.
The male sex cell from pollen grain?
The male sex cells from pollen grain are called male gametes.
