Vedclass · Answer

(B) $(i)$ In $Pteridophytes$ like $Dryopteris$, the main plant body is a sporophyte $(2n)$. The spores produced by the sporophyte germinate to form a small, multicellular, free-living, photosynthetic, thalloid gametophyte called the prothallus. Since the gametophyte is formed from spores via meiosis, it is $haploid$ $(n)$.$(ii)$ $Pteridophytes$ are the first terrestrial plants to possess vascular tissues ($xylem$ and $phloem$). Unlike $Bryophytes$ which have $rhizoids$, $Pteridophytes$ possess true $roots$, stems, and leaves.

Select the correct option for the following statements:
$(i)$ In $Dryopteris$ (fern), the prothallus is $haploid/diploid$.
$(ii)$ In $Pteridophytes$, there are $rhizoids/roots$.
