The dominant phase in the life cycle of a bryophyte is the gametophyte. A bryophyte is a type of non-vascular plant that includes mosses, liverworts, and hornworts. In their life cycle, bryophytes alternate between two distinct phases: the gametophyte phase and the sporophyte phase. The gametophyte is the dominant phase in the bryophyte life cycle, as it is the phase that performs most of the plant's functions, including photosynthesis and reproduction. The gametophyte produces gametes (sperm and egg cells) which, after fertilization, develop into sporophytes. The sporophyte is a short-lived phase in the bryophyte life cycle that produces spores, which then grow into new gametophytes, completing the cycle. Therefore, the dominant phase in the life cycle of a bryophyte is the gametophyte.
