Where can I find information about which plants have cones?

Hi. We are studying the types of plants in the Biology class and I was wondering, where can I find out which types of plants have cones. We have four different types of plants, and at least one group should have cones. The four different types of plants are: non-vascular plants, seedless vascular plants, gymnosperms, angiosperms. Please help. Thank you. I think the answer is gymnosperms, but I am not 100% sure. Thank you.

Where can I find information about which plants have cones?
The conifers, division Pinophyta, also known as division Coniferae, are one of 13 or 14 division level taxa within the Kingdom Plantae.





They are cone-bearing seed plants ( Gymnosperms)with vascular tissue; all extant conifers are woody plants, the great majority being trees with just a few being shrubs.





Typical examples of conifers include cedars, cypresses, douglas-firs, firs, junipers, kauris, larches, pines, redwoods, spruces, and yews.





Species of conifers can be found growing naturally in almost all parts of the world, and are frequently dominant plants in their habitats, as in the taiga, for example. Conifers are of immense economic value, primarily for timber and paper production; the wood of conifers is known as softwood. The division contains approximately 700 living species.

Cone is a general term used whenever the reproductive organs are in a compact cone like appearance.





Confers mentioned above are certainly in that category; but besides them , some pteridophytes like equisetum , lycopodium and selaginella also bear cones.





See below-


1) Equisetum -(Seedless Vascular plant) The spores are borne under sporangiophores





in cone-like structures (strobilus, pl. strobili) at the tips of





some of the stems. In many species the cone-bearing stems are unbranched, and in some (e.g. E. arvense) they are non-photosynthetic, produced early in spring separately from photosynthetic sterile stems. In some other species (e.g. E. palustre) they are very similar to sterile stems, photosynthetic and with whorls of branches.

2)cycas-( Gymnosperm)


It is agymnosperm that belongs to Cycadophyta . Microsporangia are borne in cones.

3) Lycopodium - ( Seedless Vascular Plant)Lycopodium is a genus of clubmosses, also known as ground pines, in the family Lycopodiaceae, a family of fern-allies (see Pteridophyta).





They are flowerless, vascular, terrestrial or epiphytic plants, with widely-branched, erect, prostrate or creeping stems, with small, simple, needle-like or scale-like leaves that cover the stem and branches thickly.





The fertile leaves are arranged in cone-like strobilli.





Specialized leaves (sporophylls) bear reniform spore-cases (sporangia) in the axils, which contain spores of one kind only. These club-shaped capsules give the genus its name.

4) Selaginella-( Seedless Vascular Plant)Spikemoss refers to any plant of the genus Selaginella in the family Selaginellaceae. Many workers still place the Selaginellales in the class Lycopsida (modern nomenclature: Lycopodiopsida). This group of plants are included in what, for convenience, is called "fern allies".
