Does a pollen grain make food for the plant?
No, a pollen grain does not make food for the plant. Pollen grains are responsible for carrying the male gametes of a plant to the female reproductive structures for fertilization. Once fertilization occurs, the plant can produce seeds for reproduction.
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 is the difference between pollen and pollen grain?
Pollen refers to the microscopic reproductive structures produced by plants, while pollen grains are the individual units that carry the male gametes. Pollen grains are released from the anthers of flowers and are carried by wind or pollinators to fertilize the ovules of plants.
Why is exine of pollen grain not a continuous layer?
The exine of a pollen grain is not a continuous layer because it has openings called germ pores or colpi, which allow for the entry of pollen tubes during fertilization. These pores are necessary for the reproductive success of the plant as they facilitate the transfer of genetic material from the male gametophyte to the female reproductive structures.

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.
Do Dicot have pollen grain?
yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores
What makes seeds when combined with a flower's eggs?
This tiny grain is called pollen grain.
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 is the difference between pollen and pollen grain?
Pollen refers to the microscopic reproductive structures produced by plants, while pollen grains are the individual units that carry the male gametes. Pollen grains are released from the anthers of flowers and are carried by wind or pollinators to fertilize the ovules of plants.

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 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
