Section " A" Subsection---"1"
Bryophytes (nonvascular Plants) are the only embryophytes (plants that produce an embryo) whose life history includes a dominant gametophyte  (haploid) stage. They are an ancient and diverse group of non-vascular plants. They comprise three main taxonomic groups: mosses  (Bryophyta), liverworts (Marchantiophyta or Hepatophyta) and hornworts (Anthocerotophyta) which have evolved quite separately.
