Sporogenous tissue → (i) →Microspore mother cells → (ii) → Microspore tetrads
Identify (i) and (ii) in the above sequence.
(i) - Mitosis, (ii) - Meiosis
Sporogenous tissue undergoes mitosis and produce many microspore mother cells. Each microspore mother cell undergoes meiosis (reduction division) to form microspore tetrads where each microspore develops and matures to form the male gametophyte or pollen grain.
