Vedclass · Answer

(B) In $Pteridophytes$,the main plant body is a sporophyte $(2n)$,which is differentiated into true root,stem,and leaves.The gametophytic stage is a small,inconspicuous,and usually free-living,photosynthetic thalloid called a $prothallus$.This gametophyte is haploid $(n)$,autotrophic,and produces male and female sex organs ($antheridia$ and $archegonia$) to form gametes.Therefore,the gametophytic stage is a secondary,short-lived,haploid,and autotrophic phase compared to the dominant sporophytic phase.
