Francesco Ambrosi
Francesco Ambrosi (November 17, 1821 – 9 April 1897) was an Italian botanist, librarian, ethnologist and historian. Biography Ambrosi was born to a family of herders in Borgo Valsugana, the present day Italian province of Trentinoat that time part of the (Princely) County of Tyrol, a crown land of the Austrian Empire. He was not able to attend school, but he pursued self-taught studies in the natural sciences, history, philosophy and, in particular, botany. He devoted himself to botany by studying under Francesco Angelo Facchini and Casimiro Sartorelli, focusing on the flora of the Trentino region. He published many scientific works, notably, in 1851, ''Prospetto delle specie zoologiche conosciute nel Trentino''. In 1853 he married Elisa Zanollo, and the couple would have eight children together, though five of died in infancy. In 1854 he began publishing the journal ''La flora del Tirolo meridionale'', which was discontinued in 1857 before he was able to complete the detaile ...

Tepals
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Rovereto
Rovereto (; "wood of sessile oaks"; locally: ''Roveredo'') is a city and ''comune'' in Trentino in northern Italy, located in the Vallagarina valley of the Adige River. History Rovereto was an ancient fortress town standing at the frontier between the bishopric of Trento – an independent state until 1797 – and the republic of Venice, and later between Austrian Tyrol and Italy. In the Middle Ages it was known by its German toponyms ''Rofreit'' and ''Rovereith''. This town started to be populated with inhabitants of the prehistory with traces that were found where today are the oldest ways which belong to the actual main historical centre, around via della Terra. The town has a complexity of plans which are printed in various developments, as if it could have different directions to evolve an ideal, brought towards its completeness in the 15th century, from the model of Siena – the leaf of the crown and the classic Athens reference of the foxil Nautilus.

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Language
German ( ) is a West Germanic languages, West Germanic language mainly spoken in Central Europe. It is the most widely spoken and Official language, official or co-official language in Germany, Austria, Switzerland, Liechtenstein, and the Italy, Italian province of South Tyrol. It is also a co-official language of Luxembourg and German-speaking Community of Belgium, Belgium, as well as a national language in Namibia. Outside Germany, it is also spoken by German communities in France (Bas-Rhin), Czech Republic (North Bohemia), Poland (Upper Silesia), Slovakia (Bratislava Region), and Hungary (Sopron). German is most similar to other languages within the West Germanic language branch, including Afrikaans, Dutch language, Dutch, English language, English, the Frisian languages, Low German, Luxembourgish, Scots language, Scots, and Yiddish.

Slovak Language
Slovak () , is a West Slavic language of the Czech–Slovak group, written in Latin script. It is part of the Indo-European language family, and is one of the Slavic languages, which are part of the larger Balto-Slavic branch. Spoken by approximately 5 million people as a native language, primarily ethnic Slovaks, it serves as the official language of Slovakia and one of the 24 official languages of the European Union. Slovak is closely related to Czech, to the point of mutual intelligibility to a very high degree, as well as Polish. Like other Slavic languages, Slovak is a fusional language with a complex system of morphology and relatively flexible word order. Its vocabulary has been extensively influenced by Latin and German and other Slavic languages. The Czech–Slovak group developed within West Slavic in the high medieval period, and the standardization of Czech and Slovak within the Czech–Slovak dialect continuum emerged in the early modern period. In the later mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosomes
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called sis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.
