WebBryophytes are nonvascular because they do not have tracheids; instead, water and nutrients circulate inside specialized conducting cells. In a bryophyte, all the vegetative … WebThe Phylum Bryophyta includes mosses, which have a dominant gametophyte generation. The gametophyte generation is responsible for producing gametes, which fuse to form a zygote. The zygote then develops into a sporophyte generation, which is dependent upon the gametophyte generation for nutrition and support. list of restore points on this computer https://edgeexecutivecoaching.com

WebThe sporophyte is barely noticeable. The gametes formed by bryophytes swim with a flagellum, as do gametes in a few of the tracheophytes. The sporangium—the multicellular sexual reproductive structure—is present in bryophytes and absent in the majority of algae. WebThe bryophyte life cycle involves two distinct stages or an alternation of generations, each with a different physical form. These are the sporophyte and gametophyte generations. Each of these stages is named for what they produce. For example, the sporophyte generation produces the spores that develop into new plants. imitation is a sign of flattery
