The mutualistic symbiotic association of a fungus with an alga or a cyanobacterium, or both. In contrast to the vascular plants, the gametophyte (haploid) generation of bryophytes constitutes the larger plant form, while the small sporophyte (diploid) generation grows on or within the gametophyte and depends upon it for nutrition. Bryophytes generally live on land but are mostly found in moist environments, for they have free-swimming sperm that require water for transport. Bryophytes lack the specialized tissues xylem and phloem that circulate water and dissolved nutrients in the vascular plants. Also called tracheophyte.Ī large group of seedless green plants including the mosses, liverworts, and hornworts.
