    The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes.The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος (γυμνός, gymnos, 'naked' and σπέρμα, sperma, 'seed'), literally meaning "naked seeds".

    www.britannica.com/plant/gymnosperm

    Gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule—unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally “naked seeds”) are borne in cones and are not visible until maturity.

    May 02, 2018 · The term gymnosperm literally means "naked seed," as gymnosperm seeds are not encased within an ovary. Rather, they sit exposed on the surface of leaf-like structures called bracts. Gymnosperms are vascular plants of the subkingdom Embyophyta and include conifers, cycads, ginkgoes, and gnetophytes. Some of the most recognizable examples of ...

  5. Gymnosperms are seed-bearing vascular plants, such as cycads, ginkgo, yews and conifers, in which the ovules or seeds are not enclosed in an ovary. The word "gymnosperm" comes from the Greek word gymnospermos, meaning "naked seeds". Gymnosperm seeds develop either on the surface of scale or leaf-like appendages of cones, or at the end of short ...

  6. Apr 28, 2017 · Gymnosperm Life Cycle. Gymnosperms reproduce with an alteration of generations, meaning their reproductive cycle has both haploid and diploid phases. As in all other vascular plants, gymnosperms have a sporophyte dominant life cycle (the sporophyte is the diploid multicellular stage, which

    Gymnosperm Plant Types. As mentioned above, gymnosperms are plants that produce seeds as a means of reproduction, but do not bear flowers. The reproductive organs and paraphernalia, both male and female, of gymnosperms, are not contained within floral structures, and are usually exposed. Now, speaking of the distinct types of gymnosperm plants ...

    Gymnosperm - Gymnosperm - Major divisions: Scottish botanist Robert Brown first distinguished gymnosperms from angiosperms in 1825. While older classifications considered all seed plants to be assignable to a single division, Spermatophyta, more-recent classifications recognize that the characteristic of naked seeds is not important enough to be used to tie all plants with that feature into ...

  9. Gymnosperms | Boundless Biology

    courses.lumenlearning.com/.../chapter/gymnosperms

    The name gymnosperm means “naked seed,” which is the major distinguishing factor between gymnosperms and angiosperms, the two distinct subgroups of seed plants. This term comes from the fact that the ovules and seeds of gymnosperms develop on the scales of cones rather than in enclosed chambers called ovaries.

    2. Seed plants originated in the Devonian p eriod from a group called the progymnosperms, which possessed wood and heterospory, but reproduced by releasing spores. Currently, five lineages of seed plants survive--the flowering plants plus four groups of gymnosperms: cycads, Ginkgo, conifers, and g netophytes.

    Seed - Seed - Gymnosperm seeds: In gymnosperms (plants with “naked seeds”—such as conifers, cycads, and ginkgo), the ovules are not enclosed in an ovary but lie exposed on leaflike structures, the megasporophylls. A long time span usually separates pollination and fertilization, and the ovules begin to develop into seeds long before fertilization has been accomplished; in some cases, in ...
