Detailed explanation-1: -The gametophyte phase is the dominant stage in the life cycle of nonvascular plants, while the sporophyte phase is the dominant stage in the seedless vascular plants’ life cycle.

Detailed explanation-2: -In vascular plants, the sporophyte generation is dominant. In seedless vascular plants such as ferns, the sporophyte releases spores from the undersides of leaves. The spores develop into tiny, separate gametophytes, from which the next generation of sporophyte plants grows.

Detailed explanation-3: -Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant.

Detailed explanation-4: -In nonvascular plants, the gametophyte generation is dominant. The tiny sporophyte grows on the gametophyte plant. In vascular plants, the sporophyte generation is dominant.

Detailed explanation-5: -The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte.
