Web29 Oct 2024 · 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. Do ferns have a dominant sporophyte generation?
WebIn terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set). In bryophytes , such as mosses and … Web9 Apr 2024 · The generation of plants that produce spores is called sporophytes. Algae, bryophytes, angiosperms, and gymnosperms make spores. A spore is a tiny structure that leads to a new plant after its germination. Spores can be of two types, namely mitotic spore and meiotic spore.
WebMore recently evolved plant lineages have multicellular shoot apical meristems (SAMs), and photosynthetic shoot development is restricted to the sporophyte generation. The molecular genetic basis for this evolutionary shift from gametophyte-dominant to sporophyte-dominant life cycles remains a major question in the study of land plant evolution. Web8 Apr 2010 · The diploid sporophyte stage of the fern cycle is dominant. In seed plants, the opposite is true; the haploid gametophyte stage is dominant for these.
