Question

Why are pollen grains non viable in microsporangium?

Answer 1

Here is your answer ⤵⤵⤵

The malfunctioning Tapetum does not nourish the developing pollen grains. Thus fails to produce viable male gametophytes. Microspore or pollen grain is the first cell of gametophytic generation. The pollen grains are preserved in liquid nitrogen at -1960C, which are used as pollen banks in crop breeding programs.
