Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organi ...

National Center For Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics.

James Apjohn
James Apjohn (1 September 1796 – 2 June 1886) was the Irish chemist known for the discovery of new minerals. Life James Apjohn (1796-1886) was a renowned and respected chemist and physicist who lived and worked in Dublin during the 1800s. He was known internationally for his work on hygrometry and the Apjohn dewpoint. A mineral from Algoa Bay, South Africa, which proved to be an effloresced manganese alum was analysed and described by Apjohn to great acclaim. Subsequently, it was named ' Apjohnite' in his honour. Apjohn was born on 1 September 1796 at his father's property, Sunville, in Pallasgrean, Co. Limerick. He attended the Tipperary Grammar School for four years before entering Trinity College Dublin in 1813 as a sizar under the tutorship of Rev. Dr. Wall. Apjohn graduated with a B.A in 1817 and took his degree of M.B in 1821. His debút as a lecturer on science took place in the Royal Cork Institution in 1824 where he succeeded Edmund Davy as Professor of Chemistry ...

Cladophora Prolifera
''Cladophora'' is a genus of reticulated Hypha, filamentous Ulvophyceae (green algae). The genus ''Cladophora'' contains many species that are very hard to tell apart and classify, mainly because of the great variation in their appearances, which is affected by habitat, age and environmental conditions. Unlike ''Spirogyra'' the filaments of ''Cladophora'' branch and do not undergo conjugation. There are two multicellular stages in its life cycle – a ploidy, haploid gametophyte and a ploidy, diploid sporophyte – which look highly similar. The only way to tell the two stages apart is to either count their chromosomes, or examine their offspring. The haploid gametophyte produces haploid gametes by mitosis and the diploid sporophyte produces haploid spores by meiosis. The only visible difference between the gametes and spores of ''Cladophora'' is that the gametes have two flagellum, flagella and the spores have four. The ''Cladophora'' species can be a major nuisance causing majo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siphonocladus Tropicus
''Siphonocladus'' is a small genus of green algae in the family Siphonocladaceae. The algal body (thallus Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms wer ...) is composed of long, club-shaped cells that divide by segregative cell division, followed by the formation of branches that break through the mother cell. As in other members of the order Cladophorales, cells are multinucleate. The genus occurs in subtropical or tropical seas, in shallow intertidal and subtidal habitats. Most species are rare.
