Vedclass · Answer

(D) The prothallus in Pteridophytes is the gametophytic stage.$1$. It is a small,inconspicuous,multicellular,free-living,and photosynthetic structure,which is haploid $(n)$.$2$. Because of its specific growth requirements,it is restricted to cool,damp,and shady places.$3$. Pteridophytes require water for the transfer of male gametes (antherozoids) to the archegonium for fertilization.$4$. The prothallus develops from a haploid spore $(n)$ produced by the sporophyte via meiosis,not from a diploid spore. Therefore,the statement that it is formed from a diploid spore is incorrect.
