Formation of Male Gametes in Angiosperms
Angiosperms are flowering plants that produce seeds enclosed in fruits. The male gametes in angiosperms are formed by the division of the generative cell, which is located within the pollen grain.
Generative Cell
The generative cell is one of the two cells that are produced by the division of the microspore mother cell during the process of microsporogenesis. The other cell is the vegetative cell, which forms the pollen tube.
Division of Generative Cell
The generative cell divides by mitosis to produce two haploid cells, which are the male gametes. These cells are released from the pollen grain and travel to the female reproductive organ, where they fertilize the egg cell to form a zygote.
Function of Male Gametes
The male gametes in angiosperms are responsible for the fertilization of the egg cell, which leads to the formation of a seed. The seed contains an embryo that develops into a new plant.
Conclusion
In conclusion, the male gametes in angiosperms are formed by the division of the generative cell located within the pollen grain. These gametes are responsible for fertilizing the egg cell, which leads to the formation of a seed.

The male gametes of angiosperms consist of two sperm cells within a pollen grain or a pollen tube. They are derived from a single GENERATIVE CELL, which is formed as the smaller cell by unequal cell division in the microspore after meiosis.
