(By “dominated” we mean “the stage of the plant you can see by eye.”) In seedless vascular plants (ferns), the sporophyte is larger than the gametophyte (the plant structure that you see is the sporophyte), but the gametophyte is free-living and independent from the diploid … WebJul 18, 2024 · On the other hand, the gametophyte of the vast majority of vascular plants is dependent on the sporophyte.
