Describe in sequence the process of microsporogenesis in angiosperms

Answer 1

Process of Microsporogenesis in Angiosperms:  

(i) When the anther develops, each cell of sporogenous tissue functions as microspore another cell (MMC) or pollen mother cell (PMC) and undergoes is meiotic divisions to form microspore tetrads.

(ii) The process of formation of microspores from a pollen mother cell (PMC) through meiosis is called microsporogenesis.  

(iii) The microspores get arranged in a cluster of four cells and hence are microspore tetrad.  

(iv) As the anthers mature and dehydrate, the microspores dissociate from each other and develop into pollen grains.  

(v) In each microsporangium, thousands of pollen grains are formed and released with the dehiscence of anther.
