Answer 2

Steps of microsporogenesis

Explanation:

• Micrsporogenesis- It is a protocol of in which microspores are developed by pollen mother cell.
• When anther builds up the cells of the sporogenous tissue experience meiotic divisions to shape microspore quadruplicates.  
• Each sporogenous tissue offers ascend to a microspore quadruplicates and is known as pollen or microspore mother cell (PMC).  
• Every microspore mother cell separates meiotically and structures 4 haploid cells or quadruplicate.  
• Each microspore separates into two inconsistent cells - enormous vegetative cells and a littler generative cell.  
• At this 2 - celled arrange the pollen grains are shed. Now and then the generative cell isolates mitotically to offer ascent to two haploid male gametes that are shed at 3 - celled arrange.
