Vedclass · Answer

(D) In heterosporous pteridophytes like $Selaginella$,the megaspores and microspores are retained and germinate within the sporangia to form female and male gametophytes,respectively.In gymnosperms like $Pinus$,the development of the male gametophyte (pollen grain) occurs within the microsporangium,and the female gametophyte develops within the megasporangium (ovule).Therefore,both $Selaginella$ and $Pinus$ exhibit the phenomenon where the primary development of gametophytes occurs within the sporangia.
