Vedclass · Answer

(B) The correct statement is that the origin of the seed habit can be traced in Pteridophytes. This is observed in heterosporous species like $Selaginella$ and $Salvinia$,where the development of the zygotes into young embryos takes place within the female gametophytes retained on the parent sporophytes. Option $A$ is incorrect because antheridiophores and archegoniophores are characteristic of Bryophytes (e.g.,$Marchantia$). Option $C$ is incorrect because the protonema and leafy stages are characteristic of the moss gametophyte (Bryophytes). Option $D$ is incorrect because in Gymnosperms,the female gametophyte is not free-living; it is retained within the megasporangium.
