microsporogenesis
Producing male spores
Microsporogenesis is the process by which microspores—the cells that develop into pollen grains—are formed in seed plants.
It occurs within the anthers of flowers, where specialized cells undergo meiosis to produce four haploid microspores from each parent cell.
The term appears primarily in botany and plant biology: The timing of microsporogenesis affects pollen viability.
