18. There are more than 1,000 species of Gymnosperms still found on Earth

19. The key difference between angiosperms and Gymnosperms is how their seeds are developed.
Gymnosperms
20. Gymnosperms include the gingkoes and conifers and inhabit many ecosystems, such as the taiga and the alpine forests, because they are well adapted for cold weather
Gymnosperms, Gingkoes
21. Gymnosperms, meaning “naked seeds,” are a diverse group of seed plants and are paraphyletic.Paraphyletic groups are those in which not all members are descendants of a single common ancestor
Gymnosperms, Group, Groups
22. Gymnosperms used to have many more species, but it is likely that the event that wiped out most of the dinosaurs also represented the end for most of those lineages
Gymnosperms
23. Extant groups of Gymnosperms include the conifers, cycads (similar in appearance to palms), gnetophytes, and single species from the ginkgophytes, Ginkgo biloba

26. Gymnosperms are an ancient group of plants that include some familiar living forms such as conifers, cycads, and ginkgos as well as a great variety of far less well-known and long-extinct kinds

34. Gymnosperms - First Plants with Seeds So you've got a vascular system.What comes next? Seeds

35. But remember this: Gymnosperms have not developed the ability to make flowers.
Gymnosperms
36. "Gymnosperms" include all seed plants other than the angiosperms, or flowering plants
Gymnosperms
37. The absence of an enclosing structure is believed to be primitive, thus the first seed plants were "Gymnosperms." The seeds of "Gymnosperms" are borne exposed in open structures, such as cones or leaves.
Gymnosperms
38. Gymnosperms are a group of plants in which are characterized by being flowerless
Gymnosperms, Group
39. Contrastingly to angiosperms, the seeds of Gymnosperms are not enclosed in an ovary or carpel.

40. Gymnosperms 5 The female cones of Ginkgo biloba are generally thought to have evolved from a branch, but all that remain are the long stalks with terminal ovules (seeds) with a thin fleshy covering
Gymnosperms, Ginkgo, Generally
41. Gymnosperms were preceded by the proGymnosperms (“first naked seed plants”)
Gymnosperms
42. Gymnosperms exhibit cones or strobili, naked seeds (= "gymnosperm"), but not flowers
Gymnosperms, Gymnosperm
43. All Gymnosperms are heterosporous and have two types of cones: male, which are smaller and female, which tend to be larger.

44. Examples of Gymnosperms are fir trees, spruce trees, pine trees, cycads and ginkgo trees

48. Gymnosperms (∼1,100 species) and Angiosperms together comprise the seed plants, which are heterosporous and keep their spores and gametophytes embedded within parental diploid tissue

GYMNOSPERMS [ˈjimnəˌspərm]
There are four major types of gymnosperms. They are conifers, cycads, ginkgo, and gnetophyte.
Differences between Pteridophytes and Gymnosperms: The sporophytic plant body is by and large arborescent in gymnosperms while it is not so in pteridophytes. Roots are adventitious in pteridophytes while they arise from the radicle (tap root) in gymnosperms. ADVERTISEMENTS: Pteridophytes may be homosporous or heterospoers, while all gymnosperms are heterosporous. More items...
Examples of gymnosperms are fir trees, spruce trees, pine trees, cycads and ginkgo trees. Examples of angiosperms include oak trees, maples, birches, forsythias, daisies, lilies and lilac bushes. Gymnosperm means "naked seed," although the seeds of these types of plants aren't found in fruit as they are in angiosperms.
Definition of gymnosperm. : any of a group of vascular plants that produce naked seeds not enclosed in an ovary, that were formerly considered a class (Gymnospermae) of seed plants, but that are now considered polyphyletic in origin and divided into several extinct divisions and four divisions with surviving members typified by the cycadophytes,...
