A protonema is a thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte (e.g., Funaria) life cycle. Funarai is gametophytic, and each gametophore consists of rhizoids, ‘stem’ and ‘leaves’ Haplo-diplontic type of life cycle involves the clear alternation of generations between a haploid gamete producing gametophyte and a diploid spore-producing sporophyte. Funaria exhibit this kind of life cycle pattern. Answer:(a)
