Male gametophyte in Angiosperms
In angiosperms, the male gametophyte or pollen grain is formed inside the anther of the flower. It undergoes a series of developmental changes to produce mature pollen that can fertilize the female gametophyte or embryo sac.
Three-celled Pollen Grain
The mature pollen grain of angiosperms is a three-celled structure consisting of a vegetative cell, a generative cell, and a tube cell. The vegetative cell is responsible for forming the pollen tube that grows towards the ovule while the generative cell divides to form two sperm cells that fertilize the egg and the central cell.
Microspore Mother Cell
The microspore mother cell, also known as the pollen mother cell, is the precursor cell that gives rise to the male gametophyte. It undergoes meiosis to form four haploid microspores that develop into pollen grains.
Anther
The anther is a part of the stamen in a flower that contains the microspore mother cells. It is responsible for producing and releasing mature pollen grains into the environment for fertilization.
Conclusion
In conclusion, the male gametophyte of angiosperms is a three-celled pollen grain that is formed from the microspore mother cell in the anther. The pollen grain plays a crucial role in fertilization by delivering the sperm cells to the female gametophyte.
