Megaspore divides twice to form an eight nucleate embryo sac

Vedclass · Answer

(C) The statement in option $C$ is incorrect because the functional megaspore undergoes three successive mitotic divisions to form an eight-nucleate embryo sac,not two.$1$. Pollen grains are typically released at the $2$-celled stage in most angiosperms.$2$. In many species,a sporogenous cell directly functions as the megaspore mother cell $(MMC)$.$3$. The functional megaspore undergoes three rounds of free nuclear mitosis to produce $8$ nuclei,which then organize into the embryo sac.$4$. The egg apparatus,consisting of the egg cell and two synergids,is always located at the micropylar end.
