Biseriate

Last updated

Biseriate is a botanical term applied to both plantae and fungi, meaning 'arranged in two rows'.

The term can refer to any number of structures found within these kingdoms, from arrangement of leaves to the placement of spores.

In biology, kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla.

Spore unit of asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions; spores form part of the life cycles of many plants, algae, fungi and protozoa

In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoebulae into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula.

It becomes useful in taxonomy for placing a species within a certain genus, family, or even order, based upon morphology, when making an initial choice or when DNA evidence is inconclusive.

Taxonomy (biology) The science of identifying, describing, defining and naming groups of biological organisms

In biology, taxonomy is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Organisms are grouped together into taxa and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a super-group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum, class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the father of taxonomy, as he developed a system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms.

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

A glossary, also known as a vocabulary or clavis, is an alphabetical list of terms in a particular domain of knowledge with the definitions for those terms. Traditionally, a glossary appears at the end of a book and includes terms within that book that are either newly introduced, uncommon, or specialized. While glossaries are most commonly associated with non-fiction books, in some cases, fiction novels may come with a glossary for unfamiliar terms.

Bend (heraldry) heraldic ordinary

In heraldry, a bend is a band or strap running from the upper dexter corner of the shield to the lower sinister. Authorities differ as to how much of the field it should cover, ranging from one-fifth up to one-third. The supposed rule that a bend should occupy a maximum of one-third of the field appears to exclude the possibility of three bends being shown together, but contrary examples exist. Outside heraldry, the term "bend sinister" is sometimes used to imply illegitimacy, though it is almost never true that a bend sinister has this significance, and a "bar sinister" cannot, by its nature, exist.

Representational State Transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, termed RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.

Perianth

The perianth is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals). The term perianth is derived from the Greek περί, peri, meaning around, and άνθος, anthos, meaning flower, while perigonium is derived from gonos, meaning seed, i.e. sexual organs. In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure.

An executive session is a portion of the United States Senate's daily session in which it considers nominations and treaties, or other items introduced by the President of the United States. These items are termed executive business; therefore, the session is an executive session. It can either be closed door or open door. Historically, as a courtesy to the President, such sessions were always held behind closed doors, but this custom has been abandoned in modern times. The term "executive session" is still employed to refer to closed-door committee meetings, whether or not they are considering executive business. In any case, those present in an executive session are sworn to secrecy.

The terms may also indicate the speakers of these languages. Traditionally, both languages are indicated by the term Yellow Uygur, from the autonym of the Yugur. Eastern Yugur speakers are said to have passive bilingualism with Southern Mongolian, the standard spoken in China.

Pseudanthium

A pseudanthium, also called a flower head or composite flower, is a special type of inflorescence, in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The individual flowers of a pseudanthium commonly are called florets. The real flowers are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large.

Rain and snow mixed

Rain and snow mixed is precipitation composed of rain and partially melted snow. Unlike ice pellets, which are hard, and freezing rain, which is fluid until striking an object, this precipitation is soft and translucent, but it contains some traces of ice crystals, from partially fused snowflakes. In any one location, it usually occurs briefly as a transition phase from rain to snow or vice versa. Its METAR code is RASN.
