==Plants that bear seed==
Vascular plants that do bear [[seed]] are divided into [[gymnosperm]]s ("naked seed") and [[angiosperm]]s (meaning "covered seed").  Gymnosperms produce seed which are only partly enclosed by tissues from the parent plant.  [[Conifer]]s form the largest gymnosperm order, with about 650 species; they bear seed on the scales of the cones they produce.  Many conifers, like [[pine]]s (''Pinus'') and [[cypress]]es (''Chamaecyparis, Cupressus'') are very important horticulturally.  Other gymnosperms include [[cycad]]s and [[ginkgo]]s. Angiosperms, also called flowering plants, differ from gymnosperms in producing their reproductive organs in flowers, with the seeds fully covered in an ovary.
