Conifers are gymnosperms or "naked seed plants" in the phylum Coniferophyta. Ferns are non-seed plants in the phylum Pterophyta. The groups have different life cycles. Ferns produce spores that develop into gametophytes. Male gametophytes produce sperm, which fertilize eggs from other gametophytes.

Cycads are placed in the Division Cycadophyta. They retain several fern-like features, notably pinnate leaves and circinate vernation. However, they usually produce cones of nonphotosynthetic reproductive structures, a distinctively unfernlike feature. Cycads, like all seed plants, are also heterosporous, unlike the ferns which are all homosporous. The Cycadophytes The Cycads are an ancient phylum, surviving through the age of the dinosaurs to modern times. Today, the cycads are divided into 3 families, 11 genera and 250 species. There is a great deal of variation within the phylum, but a few unique characteristics hold them together and differentiate them from other seed-bearing plants. Nov 25, 2015 · Therefore, angiosperms are considered to be more advanced plant group than gymnosperms.The main difference between Angiosperm and Gymnosperm is that the diversity of angiosperms is greater than that of the gymnosperms; this indicates the high adaptability of angiosperm to terrestrial ecosystems.

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.

Gnetophyta is a division of plants, grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: Gnetum (family Gnetaceae), Welwitschia (family Welwitschiaceae), and Ephedra (family Ephedraceae).

Distinguish difference between bryophytes, ferns, gymnosperms, angiosperms. Vocabulary about fertilization of various types of plants as above, especially female and male parts. Asked by a Biology student, October 18, 2015 Ferns, palms and cycads look similar thanks to their elegantly arranged, fan-like leaves. Ferns, palms and cycads can all often be found in tropical garden designs and love warm climates. Palms are evergreen flowering plants usually with feather-shaped leaves. Ferns are non-flowering plants with spores for reproduction.

There are altogether four types of gymnosperms, according to their order on the evolutionary tree: Cycadophyta, Ginkgophyta, Coniferophyta and Gnetophyta. Cycadophyta. Cycadophyta, or the Cycads, first appeared in the Carboniferous period around 320 million years ago and were the dominant land plant at the time of the dinosaurs. The gymnosperms include 4 divisions: Coniferophyta, Cycadophyta, Ginkgophyta, and Gnetophyta. Ginkgo trees are widely planted in New York City, e.g., nearby in Madison Square Park, because they are resistant to pollution. The leathery, fan-shaped leaves are borne close to the stem and not from the tips of twigs. Trees are male or female. Distinguishing characteristics of the phylum Gnetophyta include the presence of both tracheids and vessels in their xylem tissue, a unique fertilization feature in which a tube grows from the eggs to unite with pollen tubes, and being the only division of gymnosperms that undergo double fertilization. Ferns, palms and cycads look similar thanks to their elegantly arranged, fan-like leaves. Ferns, palms and cycads can all often be found in tropical garden designs and love warm climates. Palms are evergreen flowering plants usually with feather-shaped leaves. Ferns are non-flowering plants with spores for reproduction. Also, there is a difference in the gametophytic life cycle stages between ferns and gymnosperms wherein ferns have complex liberally surviving gametophytes unlike gymnosperms. Summary : 1.Ferns are flowerless plants that do not have any seeds whereas gymnosperms do have seeds of their own.
