In bryophytes the gametophytic generation is the dominant phase in the life cycle and the sporophyte phase is dependent upon it whereas in angiosperms, the sporophyte is the dominant phase and the gametophyte is dependent upon it. Both have a dominant sporophytic generation.

Here, the dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis. The spores are produced by the sporangia in the spore mother cells. gametophyte is dominant in bryophytes whereas the sporophyte is dominant in pteridophytes. - Sporophyte is the dominant generation. - Sporophyte is the green fern plant, is larger and longer-lived phase of life cycle.
