Trace the development of microsporocyte in the anther to a mature pollen grain.

Explanation

Microsporophyte or microspore mother cells/ pollen mother cells are polygonal and closely packed in microsporangia initially. Pollen grains develop from them in pollen sacs of anthers. As anther enlarges, pollen mother cells lose cytoplasmic connections and become loosely arranged.
A few microsporocytes become non functional and are absorbed by developming microspores. Each microsporocyte becomes rounded, undergoes meiosis and forms four haploid cells microspores or pollen grains.
They are arranged in tegrahedral manner Later on front each tetrad, microspores separate and develop into a mature pollen grain.
