Gymnosperms are a group of plants that share one common characteristic: they bear seeds, but their seeds do not develop within an ovary. For this reason, gymnosperms were long thought to be an evolutionary precursor to the angiosperms, which are seed plants that enclose their seeds in an ovary and that are vastly more diverse than gymnosperms.

  Gymnosperms came from the Greek root "gymnos" or "naked" with "sperma"or "seed". In other words, gymnosperms are naked seeded plants. Although the ovules are naked at the time of pollination, the seeds of gymnosperms are sometimes enclosed by other sporophyte tissues by the time they are mature. There are four group of living gymnosperms such.   "The Plant-Book is widely accepted as an essential reference text for anyone researching, growing or writing about plants. In o entries this comprehensive dictionary provides information on every family and genus of seed-bearing plants (including gymnosperms) plus ferns and other pteridophytes, combining taxonomic details with Author: Brad Brazzeal.

Gymnosperms are older than angiosperms on the evolutionary scale. They are found far earlier in the fossil record than angiosperms. As will be discussed in subsequent sections, the various environmental adaptations gymnosperms have represent a step on the path to the most successful (diversity-wise) clade (monophyletic branch).   Do all gymnosperms have cones? These questions and many others are answered in Gymnosperms of the United States & Canada. This user-friendly reference was written by Dr. Elray S. Nixon and illustrated by Bruce Lyndon Cunningham.
