That classification is based on a mixture of molecular, morphological (macroscopic and microscopic) and cell structure data and, for the sake of brevity, will be referred to as the 2000 classification on this web page. net carbon gain. The pre-Cenozoic bryophyte fossil record is significantly sparser than that of vascular plants or Cenozoic bryophytes. Branches develop from surface cells in the originating stem and in most mosses branches are simple, single outgrowths from the originating stems. The fuzzy green covering encasing most available surfaces in this forest is moss, a type of bryophyte. That statement is so close to the whole truth that it's no surprise it's so commonly used.

They are best known for those species that carpet woodland and forest floors. The "bryophytes" comprise three phyla of plants united by a similar haploid-dominant life cycle and unbranched sporophytes bearing one sporangium: the liverworts (Marchantiophyta), mosses (Bryophyta), and hornworts (Anthocerophyta). There In a dry moss plant the leaves are typically folded into or curled around the stems. As they are not flowering plants, bryophytes reproduce by spores instead of seeds.
