Ploidy
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Here ''sets of chromosomes'' refers to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair—the form in which chromosomes naturally exist. 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 sets of chromosomes. 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 o ...

Richard Anthony Salisbury
Richard Anthony Salisbury (born Richard Anthony Markham; 2 May 1761 – 23 March 1829) was a British botanist. While he carried out valuable work in horticultural and botanical sciences, several bitter disputes caused him to be ostracised by his contemporaries. Life Richard Anthony Markham was born in Leeds, England, as the only son of Richard Markham, a cloth merchant and Elizabeth Laycock. His family included two sisters, including his older sister Mary (b. 1755). One of his sisters became a nun. His mother, was the great grand-daughter of Jonathan Laycock of Shaw Hill. Laycock in turn married Mary Lyte (b. 1537), brother of Henry Lyte (botanist), Henry Lyte, the botanist and translator of the herbal of Rembert Dodoens, Dodoens. Of this, he wrote "so I inherit a taste for botany from very ancient blood". He studied at a school near Halifax, West Yorkshire, Halifax and by the age of eight had established a passion for plants. He attended medical school at the Univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nymphaea Subg
''Nymphaea'' () is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, ''nymphaia'' and the Latin ''nymphaea'', which means "water lily" and were inspired by the nymphs of Greek and Latin mythology. Description Vegetative characteristics Water lilies are aquatic, rhizomatous or tuberous, perennial or annual herbs with sometimes desiccation-tolerant, branched or unbranched rhizomes, which can be stoloniferous, or lacking stolons. The tuberous or fibrous roots are contractile. The leaves are mostly floating, but submerged and emergent leaves occur as well. The shape of the lamina can be ovate, orbicula ...

Plants Described In 1811
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Flora Of Japan
The flora of Japan comprises a large assemblage of plant species which can be found in Japan, such as sakura, katsura (tree), katsura, momiji and azalea. There are many species which are endemic to Japan. Diversity Japan has significant diversity in flora. Of approximately 5,600 total vascular plant species, almost 40% are endemic. This richness is due to the significant variation in latitude and altitude across the country, a diversity of climatic conditions due to monsoons, and multiple geohistorical incidences of connections with the mainland. Vegetation types Japan consists of roughly 4 vegetation classification, vegetation zones that are delineated by temperature and precipitation: the alpine region, subalpine region, summer-green broad-leaved forest region and Taiheiyo evergreen forests, evergreen broad-leaved forest region. Due to its substantial length of over 3,000 km from north to south and its mountain ranges that can exceed 3,000 meters, Japan's vegetation v ...
