Question

Describe in sequence the processes 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.

All the very best for exams

Answer 2

It is the process in which each mother cell meiotically divides into four pollen grains or haploid microspores.

• The sequence for the same is -

• When the anther typically develops each sporogenous tissue cell undergoes meiotic divisions to form tetrads of microspore.
• Each properly represents a mother cell (MMC) with a microspore.  
• Microspore formation phase from a pollen mother cell is known as meiosis  
• The microspores are then arranged in a four-cell ring and efficiently are, therefore, microspore tetrad.  
• As anthers ripen and dehydrate, dissociated microspores from each ample ether, and sufficiently develop in pollen grains.  
• Hundreds of pollen, from adequately developing microsporangium through the grain dehiscence that is typically formed and released
