Horsetails gametophyte or sporophyte dominant
WebSporophyte (2n)is the dominantlife cycle stage. Gametophyte (n)is smalland ephemeral/seasonal. (The "dominant" life cycle stage is larger and more conspicuous.) Across plant taxa, homologous life cycle stageshave undergone extensive evolution, and may look different from taxon to taxon. x x x x x x WebIn seedless vascular plants, the sporophyte became the dominant phase of the lifecycle. Water is still required for fertilization of seedless vascular plants, and most favor a moist environment. Modern-day seedless tracheophytes include club mosses, horsetails, ferns, and whisk ferns.

WebThe sexual phase, called the gametophyte generation, produces gametes, or sex cells, and the asexual phase, or sporophyte generation, produces spores asexually.
