$(a)$ Liverworts (e.g.,Marchantia) show a thalloid body. The female thallus bears archegoniophores,while the male thallus bears antheridiophores. Both possess gemma cups and rhizoids.
$(b)$ In Funaria (a moss),the gametophyte is the dominant,independent,green,leafy stage. The sporophyte is differentiated into a foot,seta,and capsule,and it remains attached to the gametophyte for nutrition.
$(c)$ Angiosperms exhibit a diplontic life cycle where the sporophyte $(2n)$ is the dominant phase. The gametophyte $(n)$ is highly reduced. The cycle involves the production of microspores and megaspores,leading to fertilization and the development of the embryo within the seed.
