Solution (By Examveda Team)

The process of development of pollen grains in anther of the stamen is Microsporogeneis.
It is the meiotic or reduction division process that produces pollen grains (or microspores) inside the pollen sacs (or microsporangium) of flowering plants.
Microsporogenesis is an important process in plant reproduction, which includes several series of developmental stages from sporogenous cells to microspores.
Any unpredictable disturbance during the meiotic process reduces gamete viability.
