Vedclass · Answer

(D) In bryophytes,including mosses,the life cycle exhibits a dominant gametophytic phase $(n)$.The sporophyte $(2n)$ is formed after the fusion of gametes (syngamy) to form a zygote,which develops into the sporophyte.The sporophyte is not free-living; it remains attached to the photosynthetic gametophyte for nutrition.Therefore,the sporophyte is partially or totally dependent (parasitic) on the gametophyte for its nourishment.
