- C.(3) B, D, C, A
- D.(4) A, D, C, B
Correct Answer
(B) (2) B, D, A, C
Solution & Explanation
Answer: B (option 2: B, D, A, C). The sequence of microsporogenesis begins with the compactly arranged sporogenous tissue (B) at the centre of the young microsporangium. Its cells act as pollen mother cells / microspore mother cells (D), which undergo meiosis to form clusters of four cells, the microspore tetrads (A). As the anther matures the microspores dissociate and mature into pollen grains (C). Hence the order is B → D → A → C. NCERT: Ch 1, p.6, lines 3-9 — "As each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad. Each one is a potential pollen or microspore mother cell. The process of formation of microspores from a pollen mother cell (PMC) through meiosis is called microsporogenesis... As the anthers mature and dehydrate, the microspores dissociate from each other and develop into pollen grains."
