Question

What is microsporogenesis how can I define it

Answer 1

The process of formation of microspores meiotically from a microspore mother cell is called microsporogenesis.
The sporogenous tissue consists of a group of compactly arranged homogenous diploid cells called microspore mother cells. These microspore mother cells divide meiotically to form haploid microspores, which arrange themselves in a tetrad. Microsporangium and microspores undergo changes during maturation. Microsporangium develops into the pollen sacs that extend longitudinally through the length of the anther. The microspores separate from the tetrad and develop into pollen grains.
