Vedclass · Answer

(D) The fern prothallus is the gametophytic stage in the life cycle of a fern. In the life cycle of pteridophytes,the main plant body is a sporophyte $(2n)$,which produces spores through meiosis. These spores germinate to form a small,multicellular,free-living,photosynthetic thalloid structure called the prothallus. Since the prothallus is the gametophyte,it is haploid $(n)$ in nature. Therefore,the cells of the fern prothallus contain a nucleus with $n$ chromosomes.
