Vedclass · Answer

(B) During the process of megasporogenesis,the megaspore mother cell undergoes meiosis to produce four haploid megaspores.In the majority of flowering plants,three of these four megaspores degenerate,while only one megaspore remains functional.This functional megaspore develops into the female gametophyte (embryo sac).Therefore,the correct answer is $3$ megaspores degenerate and $1$ megaspore remains functional.

Column-$I$	Column-$II$
$(a)$ Synergids	$(1)$ Female gamete
$(b)$ Central cell	$(2)$ Chalazal end
$(c)$ Antipodals	$(3)$ Filiform apparatus
$(d)$ Egg cell	$(4)$ Polar nuclei

In a majority of flowering plants,out of the four megaspores,........ megaspores degenerate and ........ megaspore remains functional.
