microsporogenesis in Science
microsporogenesis
  (mī'krə-spôr'ə-jěn'ĭ-sĭs)   
The formation of microspores inside the microsporangia (or pollen sacs) of seed plants. A diploid cell in the microsporangium, called a microsporocyte or a pollen mother cell, undergoes meiosis and gives rise to four haploid microspores. Each microspore then develops into a pollen grain (the microgametophyte).
