Vedclass · Answer

(B) The development of seed habit is a significant evolutionary trend in plants. $Heterospory$ is the production of two different types of spores,microspores and megaspores,which is a prerequisite for the development of seed habit. In heterosporous plants,the megaspore is retained within the parent sporophyte for a variable period,where it develops into the female gametophyte. This retention and germination of the megaspore within the megasporangium is the key step that leads to the formation of seeds.
