Options
- AA-II, B-III, C-I, D-IV
- BA-III, B-II, C-I, D-IV
- CA-III, B-II, C-IV, D-I
- DA-II, B-III, C-IV, D-I
Correct answer
C. A-III, B-II, C-IV, D-I
Step-by-step solution
Sporogenous tissue occupies the centre of each microsporangium in a young anther (A-III). Each cell of the sporogenous tissue acts as a Pollen mother cell (PMC) which undergoes meiosis (B-II). The result of this meiosis is a Microspore tetrad, which is a cluster of four haploid cells (C-IV). As the anther matures and dehydrates, the microspores dissociate and develop into Pollen grains, which represent the male gametophyte (D-I). Therefore, the correct matching is A-III, B-II, C-IV, D-I. Answer: A-III, B-II, C-IV,
