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 kind of spore becomes a pollen grain in seed plants?
The microspore after resulting from meiosis in the microspore mother cell become pollen grain. It takes place inside the anther lobe in the sporogenous tissue and the entire process is called microsporogenesis.
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.
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.

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.
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?

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.
