Ophioglossum Vulgatum
''Ophioglossum vulgatum'', commonly known as adder's-tongue, southern adder's-tongue or adder's-tongue fern, is a species of fern in the family ''Ophioglossaceae''. The chloroplast genome was reported to have a size of 138,562 base pairs. Description ''Ophioglossum vulgatum'' grows from a rhizome base to 10–20 cm tall (rarely to 30 cm). It consists of a two-part frond, separated into a 4-12 cm rounded diamond-shaped leaf sheath and narrow branchless spore-bearing spike. The spike has around 10-40 segments on each side. It reproduces by means of spores. Taxonomy Carl Linnaeus, Linnaeus species description, described adder's-tongue with the binomial nomenclature, binomial ''Ophioglossum vulgatum'' in his ''Species Plantarum'' of 1753. Distribution It is native to many regions with a wide scattered distribution: throughout temperate through tropical Africa and throughout the temperate Northern Hemisphere in Europe, northeastern North America, temperate Asia, and Euras ...

Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
