Heterospory

Vedclass · Answer

(A) : The differentiation of spores into microspores and megaspores,known as heterospory,is a crucial evolutionary step. The retention of the megaspore within the megasporangium on the parent sporophyte for development into the female gametophyte is considered an essential prerequisite for the formation of seeds,which is a characteristic feature of spermatophytes. This process allows the embryo to develop while being protected and nourished by the parent plant.

Which one of the following is considered important in the development of seed habit?
