The pollen is actually nothing but sperm in a protective layer. The pollen is given to various organisms which give to other plants, and then the plants take the fertilization and use it to reproduce, to make fruits, and various other things depending on the species.
In a grain of pollen,what is the function of the sperm cell that doesn't join with the egg cell?
I'd say pollen
seeds
Yes, the pollen cell is a plant cell.
The part of the cell that controls a pollen grain is the nucleus, which contains the genetic material (DNA) that regulates the cell's functions and development. Additionally, the cell membrane plays a crucial role in controlling the movement of substances in and out of the pollen grain. Together, these structures help ensure proper growth and function of the pollen grain during fertilization processes in plants.
It has pollen cell
R.B.C have hemoglobin molecule which carry carry oxygen
The stigma, a key part of the flower's reproductive structure, is adapted to effectively receive pollen for fertilization. Its surface is often sticky or feathery, which helps trap pollen grains and facilitates their adherence. Additionally, the stigma's position, usually elevated above the other floral parts, increases the likelihood of pollen landing on it from visiting pollinators. These adaptations ensure successful pollen transfer and enhance reproductive success in plants.
It is the sperm of plants.The pollen cells goes to the female reproductive part of the plants through the wind,insects etc. It goes inside makes seeds the seeds mature they make new plants.
The villi is only one cell thick so it easier to absorb.
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
it is stick so therefore it holds the pollen in place.
