Solution:
Each microsporangium has 25 microspore mother cells and hence 25 tetrads are formed upon meiosis, Each anther having 4 sacs and hence has 25X4=100 microspore tetrads.
Total number of microspore tetrad formed in a dithecous anther if each microsporangia has 25 microspore mother cells would be
