A bilobed, dithecous anther has 100 microspore mother cells per microsporangium. How many male gametophytes this anther can produce ?

Explanation

The anther is a four-sided (tetragonal) structure consisting of four microsporangia located at the corners, two in each lobe.
Each microspore mother cell gives rise to a microspore tetrad which develops into male gametophyte. So, the total number of male gametrophyte is `4 xx 400 = 1600`.
