It remains attached to the gametophyte (the haploid mother), and is in fact, parasitic upon it. protonema may be rather different in different moss- species. The fern sporophyte, the leafy frond, is independent and the dominant generation. This website uses cookies to improve your experience while you navigate through the website. Undergraduate; Graduate/ Professional; Adult Education; Get info. Plants reproduce via asexual reproduction as well as via sexual reproduction. 3. The life cycle of mosses. (I) Protonema, and, (II) Gametophore. During the evolution of plant life, a variation can be seen in the development of the reproductive system of a plant depend… The sporophyte is prominent over the gametophyte in ferns. Both gametophyte and sporophyte are multicellular structures. And speaking of reproduction, moss has a pretty handy way of accomplishing this feat as well. One is sexual, while the other is asexual. There are several differences between gametophyte and sporophyte stages. Female and male gametophytes are present in the same structure. These spores are now responsible for the development of gametophyte. The sporophyte generation of mosses is completely dependent on the gametophyte and never makes independent contact with the substrate. to be an mesh. In the latter the immature setae are so contorted that the young spore capsules are held down amongst the leaves of the cushion composed of massed gametophyte plants. Spore Formation: Production of spores occurs in the capsules, connected to the gametophytes by a stalk. The sporophytes are created by the merging of gametophyte sex cells. No Signup required. This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation. The picture on the right shows a such. 1. In mosses this is totally different. In all mosses the antheridia are more or less club shaped or. Moss sporophytes may easily be mistaken for part of the moss gametophyte plant, because they often grow up right from the gametophyte carpet.

Statement I Foot of moss sporophyte is a well organised structure. A moss sporophyte is usually a tall stalk with a round sporangium on top. This phase in the life cycle of a plant is the asexual, spore-bearing generation of the plant, featuring diploid cells. Morphological characters from the gametophyte and sporophyte generations have been used in land plants to infer relationships and construct classifications, but sporophytes provide the vast majority of data for the systematics of vascular plants. Zygotes and their resulting sporophytes are diploid. By the process of meiosis (reduction division), this sporophyte produces haploid spores. The gametophytes develop antheridia. Archegonia and. The antheridia produce motile sperms. The. (I) Foot (II) Seta & (III) Capsule. Thus, gametophyte phase is the sexual, gamete producing stage in the life cycle of the plant. Of the three phyla of bryophytes, greatest species diversity is found in the mosses, with up to 15,000 species recognized. The embryo sporophyte develops in a female sex organ called archegonium. It will develop a foot that attaches to the gametophyte. The sporophyte is the diploid phase of the alternation of generations, a method which allows sexual and asexual reproduction to prevent destructive genes to be reproduced. Moss, (division Bryophyta), any of at least 12,000 species of small nonvascular spore-bearing land plants. The sporophyte, which may be non-green, has a capsule holding spores, on the end of a stalk, and grows up occasionally, out of the ovary of the gametophyte.
