Dicranella (plant)
''Dicranella'' is a genus of moss belonging to the family Dicranaceae. The genus was first described by Karl Müller. It has a cosmopolitan distribution. ''Dicranella heteromalla'' is found to have a satisfactory holotype. ''Dicranella heteromalla'' possesses an structured designed to endure acidic environments. In addition, it has multipurpose systems that allow a satisfactory adaption. For example, the wild rhizoid system of ''D. heteromalla'' forms a dense, matted network of filaments of different diameters, which evidences that its major role is solute uptake rather than anchorage.

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Dicranaceae
Dicranaceae is a family of haplolepideous mosses (Dicranidae) in class Bryopsida. Species within this family are dioicous Dioicy () is a sexual system where archegonia and antheridia are produced on separate gametophytes. It is one of the two main sexual systems in bryophytes. Both dioicous () and monoicous gametophytes produce gametes in gametangia by mitosis ra .... Genera in this family include '' Dicranum'', '' Dicranoloma'', and '' Mitrobryum''. Classification The family Dicranaceae contains the following genera: *'' Anisothecium'' *'' Aongstroemia'' *'' Aongstroemiopsis'' *'' Braunfelsia'' *'' Brotherobryum'' *'' Bryotestua'' *'' Camptodontium'' *'' Campylopodium'' *'' Chorisodontium'' *'' Cnestrum'' *'' Cryptodicranum'' *'' Dicnemon'' *'' Dicranella'' *'' Dicranoloma'' *'' Dicranum'' *'' Diobelonella'' *'' Eucamptodon'' *'' Eucamptodontopsis'' *'' Holomitriopsis'' *'' Holomitrium'' *'' Hygrodicranum'' *'' Leptotrichella'' *'' Leucoloma'' *' ...

Karl Müller (bryologist)
Karl Johann August (Friedrich Wilhelm) Müller (16 December 1818 – 9 February 1899) was a German bryologist and science popularizer. Prior to 1843 he worked as a pharmacist at several locations in Germany ( Kranichfeld, Jever, Detmold and Blankenburg am Harz),Müller, Karl @ NDB/ADB Deutsche Biographie followed by studies in at the (1843 to 1846).

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizoid
Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the root hairs of vascular land plants. Similar structures are formed by some fungi. Rhizoids may be unicellular or multicellular. Evolutionary development Plants originated in aquatic environments and gradually migrated to land during their long course of evolution. In water or near it, plants could absorb water from their surroundings, with no need for any special absorbing organ or tissue. Additionally, in the primitive states of plant development, tissue differentiation and division of labor was minimal, thus specialized water absorbing tissue was not required. The development of specialized tissues to absorb water efficiently and anchor themselves to the ground enabled the spread of plants to the land. Description Rhizoids absorb water mainly by capillary action, in which water moves up between threads of rhizoids and not through ea ...
