Question

The cells of sporogenous tissue undergo $\dots$ divisions to form microspore tetrads.

• A. Meiotic
  
• B. Amitotic
  
• C. Mitotic
  
• D. Cleavage
  

Answer 1

The correct option is A Meiotic


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

Microsporogenesis involves the following steps:-
Each cell of the sporogenous tissue is capable of acting as a microspore mother cell.
The microspore mother cell divides by meiosis to produce a group of 4 haploid cells called microspore tetrad.
As the anthers mature and dehydrate, the microspores dissociate from each other and develop into pollen grains.

Amitotic division
Amitosis is a simple form of cell division where the appearance of chromosomes and spindle formation is absent. Examples include cell division in bacteria and yeast.

Cleavage
Cleavage is the repeated mitotic division in the zygote which results in the formation of an embryo.

Final answer
(b) Meiotic
