Question:
How far does salaginella one of the living members of pteridophytes fall short of seed habit
Answer:
In Salaginella, the megaspores and microspores germinate and give rise to female and male gametophytes, respectively. The female gametophytes in these plants are retained on the parent sporophytes for variable periods. The development of the zygotes into young embryos take place within the female gametophytes. This event is a precursor to the seed habit considered an important step in evolution.
