A vascular nonflowering plant (commonly known as a conifer) in which seeds are “naked”—collected in a cone and not protected by an ovary. The dispersion of their spermatozoids often relies on wind.

(jim´ no sperm) [Gr. gymnos: naked + sperma: seed] • A plant, such as a pine or other conifer, whose seeds do not develop within an ovary (hence, the seeds are "naked").

a plant which holds its seeds in cones.

A plant whose seeds do not develop within an ovary. Naked seeds, i.e. a pine tree.

plants of the class Gymnospermae having seeds not enclosed in an ovary

a plant with a naked seed , there being no proper ovary the seeds being fertilised by the pollen coming into direct contact with the foramen of the ovule without the intervention of a stigma

Plant that bears naked seeds. Representatives of this group include the conifers.

JIM-no-sperm Naked seed plant. 492

a plant producing seeds not enclosed in a seed case or ovary.

Term used to refer collectively to the non-flowering seed plants, in which the ovules are borne exposed, such as on the surface of sporophylls, rather than being enclosed within an ovary. (G. gymno, naked, bare + sperma, seed)

A vascular plant that bears naked seeds not enclosed in any specialized chambers.

The class of plants having naked seeds (not enclosed in an ovary). Within this group are all trees yielding softwood lumber.

plants that have an exposed seed. Examples: conifers and evergreens

a seed-bearing plant with the ovules borne on the surface of a sporophyll. cf. angiosperm.

A seed-bearing plant with ovules, and hence seeds, developing on the surface of a leaf. Parent Term: Plant_groups Difficulty Level

A plant whose seeds are not enclosed in flowers. Most gymnosperms produce their seeds on the surface of the scales of female cones and are pollinated by wind. Conifers are the most common type of gymnosperm.

n. A plant that produces seeds, which are not enclosed; includes any seed plant that does not produce flowers.

plants which are pollinated by direct contact between the pollen and the female ovule which is naked (without flower parts)

Cone bearing plants. [ edit

A seed plant which bears naked seeds, without an ovary. These plants of ancient lineage include the conifers so characteristic of the North Country as well as the gingko and ephedra of warmer climes. From the Greek, gumnos ( gymnos), "naked."

Gymnosperms are seed-bearing plants that that don't produce flowers. They release pollen into the air to the female ovule, causing fertilization. Their seeds develop without a protective covering. The earliest gymnosperms were seed ferns from the Devonian period (408-360 million years ago). Conifers (like pines, redwoods, and gingkos), and cycads are gymnosperms.

Gymnosperms (meaning "naked seeds") are seed-bearing plants that don't produce flowers. These plants release pollen into the air to the female ovule, causing fertilization. Their seeds develop without a protective covering. The earliest gymnosperms were seed ferns from the Devonian period (408-360 million years ago). Some examples of gymnosperms are conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads. These plants were very important to plant-eating dinosaurs.

Gymnosperms (Gymnospermae) are a group of seed-bearing plants with ovules on the edge or blade of an open sporophyll, the sporophylls usually arranged in cone-like structures. The other major group of seed-bearing plants, the Angiosperms, have ovules enclosed in a carpel, a sporophyll with fused margins. The term gymnosperm comes from the Greek word gumnospermos, meaning "naked seeds" and referring to the unenclosed condition of the seeds, as when they are produced they are found naked on the scales of a cone or similar structure.
