What does the reproduction of mosses ferns gymnosperms and angiosperms have in common?
i don't know it's difficult
At this level of taxonomy, there are gymnosperms and angiosperms. The gymnosperms have 'naked seed'. (Hence the gymno part of the name) The angiosperms have an ovary for producing seed, in conjunction with pollen. Earlier taxonomy has the ferns, mosses, and the non-vascular plants, seaweeds, and in New Zealand we have a a few species of Tmesipteris. These early plants do not have flowers, but the ferns at least have sexual reproduction.
Angiosperm. Angiosperms are flowering plants, and gymnosperms (are plants with naked seeds) are mostly conifers and cycads. Basically, angiosperms are plants with flowers, gymnosperms are all other vascular seed plants that don't have flowers. (There are other plants like ferns and mosses that don't fit into either groups.) Strawberries, you probably know, have flowers. They are actually in the rose family, Rosaceae.

Two ways scientists can divide vascular plants are into seedless vascular plants and seed plants. Seedless vascular plants are comprised of the lycophytes (club mosses, spike mosses, and quillworts) and pterophytes (ferns, horsetails, and whisk ferns) and do not produce seeds. Seed vascular plants are comprised of gymnosperms (ginkgo, cycads, gnetophytes, and conifers) and angiosperms (flowering plants). Gymnosperms can be distinguished by their "naked seeds," while angiosperms produce flowers and fruits.
Plants have following major classical groups . 1; Spermatophyta (seed plants ) including Angiosperms and Gymnosperms. 2 ; Pteridophyta (spore producing plants eg club mosses. 3 ; Bryophyta ( Non vascular plants ) eg liverworts. Only spermatophyta are seed producing plant and they reproduce by seed. Spermatophyta are most highly developed plants. Angiosperms are flowering plants . Gymnosperms are coniferous plants.
What are the spore bearing structures in club mosses and horsetails and the cones of gymnosperms called?
Plants are divided into the following divisions: Plants are divided into Mosses and Vascular Plants Mosses are not divided Vasular Plants are divided into Seedless Plants (Ferns) and Seeded Plants. Seedless Plants are not divided. Seeded Plants are divided into Naked Seeds (Gymnosperms) and Ovaries/Flowers (Angiosperms). For a diagram of these divisions and more information, go to the Related Link.
Because ferns (Pteridophyta) and gymnosperms are part of the larger category of vascular plants (Tracheophyta) and share common features that mosses lack. Perhaps also because of the spurious notion that "seed ferns" (Pteridospermatophyta), the ancestors of the gymnosperms, evolved from ferns. In fact, "seed ferns" are a large, heterogeneous category of plants which are generally believed to be only distantly related to true ferns.
Club mosses (Phylum Lycopodophyta) and horsetails (Phylum Equisetophyta) are similar to ferns (Phylum Pteridophyta) in that they; - do not produce seeds, only spores - have stems that are unstrengthened by wood (evolved first in the more advanced gymnosperms) - have a dominant sporophyte generation - do have vascular tissue (not as advanced as seed plants but there nonetheless) - do not produce flowers (flowers evolved first in angiosperms)
No, angiosperms do not need water to reproduce. Bryophytes, or mosses, need water to reproduce-the sperm cells swim to the egg by following a trail of chemicals in the water. Thus, mosses reproduce in wet, rainy seasons of the year. Angiosperms, on the other hand, do not require water because the stamen releases male gametophytes, pollen grains, that are carried by the wind to the egg in the carpel.
Yes there is a difference. Biologically a plant has roots, stems and leaves; a flower is part of the reproductive system of a plant, although not all plants have flowers! Ferns and moss for example reproduce by spores (and not seed) although they are plants. Angiosperms have flowers, whereas mosses, ferns and gymnosperms do not have true "flowers". There is also a common naming issue which complicates matters, in the US some people simply refer…
Plants are first classified as to whether or not they have vascular tissue, like xylem and ploem, which act as transportation mechanisms. Non-vascular plants, bryophytes, include moss and liverwort. Vascular plants, tracheophytes, are then further classified as to whether or not they produce seeds. Seedless plants produce by spores, like ferns. These are primitive plants. Seed plants are then further classified into angiosperms or gymnosperms. Angiosperms are flowering plants, and include lemons and apples. Gymnosperms…

From Wikipedia: The gymnosperms are a group of seed-bearing plants that includes conifers, cycads, Ginkgo, and Gnetales. The term "gymnosperm" comes from the Greek word gymnospermos (γυμνόσπερμος), meaning "naked seeds", after the unenclosed condition of their seeds (called ovules in their unfertilized state). Their naked condition stands in contrast to the seeds or ovules of flowering plants (angiosperms), which are enclosed during pollination. Gymnosperm seeds develop either on the surface of scale- or leaf-like appendages…
Mosses belong to the division Bryophyta. Bryophytes are generally terrestrial plants but they need water in order to reproduce. As moss is a bryophyte even it is a terrestrial plant which needs abundant moisture for growth and reproduction. So mosses (Bryophytes) are called the amphibians of the Plant Kingdom.
Kingdom Plantae is divided into subkingdoms Tracheobionta and Spermatophyta, as well as a miscellaneous category. Perhaps the most important phyla are bryophytes (mosses and ilk), pteridophytes (ferns and ilk), pteridophytes (conifers and ilk), and then angiosperms (flowering plants) in order of emergence in the evolutionary record. Today angiosperms are the most widespread.
