Vedclass · Answer

(B) In the process of megasporogenesis,a single megaspore mother cell $(MMC)$ undergoes meiosis to form four haploid megaspores. In most angiosperms,including $Capsella$,the three megaspores towards the micropylar end degenerate,while the single megaspore towards the chalazal end remains functional. This functional megaspore develops into the female gametophyte (embryo sac). Therefore,the functional megaspore is always located at the chalazal end.
