Question

The microspores, as they are formed, are arranged in a cluster of four cells - the microspore tetrad. As the anthers mature and dehydrate, the microspores dissociate from each other and develop into

• A. Both A and C
  
• B. Pollen grains
  
• C. Male gametophyte
  
• D. Female gametophyte
  

Answer 1

The correct option is A Both A and C


Microsporogenesis
Microsporogenesis is the development of microspores from the microspore mother cells.

Microsporogenesis involves the following steps:
Each cell of the sporogenous tissue present at the center of the microsporangium is capable of developing into a microspore mother cell.
The microspore mother cell divides by meiosis to produce a tetrad of haploid cells called microspore tetrad.
As the anthers mature and dehydrate, the microspores dissociate from each other and develop into pollen grains.


Male gametophyte
The pollen grains are haploid cells which represent the male gametophyte because the male gametes are formed from them.

Final answer
(d) Both A and C
