Question

21. Describe the structure of a bilobed and dithecous anther as seen in transverse section​

Answer 1

Each microsporangium has 100 microspore mother cells which form 400 microspores by meiosis (100 × 4).
In an anther, there are four microsporangia. So, the total number of microspores will be 4 × 400 = 1600.
As each microspore forms one male gametophyte, 1600 male gametophytes can be produced.
