Q.Which of the plant group has gametophyte as a dominant phase?

Bryophytes are the plant group in which the gametophyte (not the sporophyte) is the dominant, free-living phase of the life cycle.

All plants alternate between two multicellular phases: the haploid gametophyte, which produces gametes, and the diploid sporophyte, which produces spores. Which phase dominates (is larger, longer-lived, and photosynthetic) differs across plant groups:

• In Bryophytes, the green, leafy or thalloid plant body we see is the GAMETOPHYTE. The sporophyte is much smaller, often just a capsule on a stalk, and remains permanently attached to and nutritionally dependent on the gametophyte. …
