Manioc
''Manihot esculenta'', common name, commonly called cassava, manioc, or yuca (among numerous regional names), is a woody shrub of the spurge family, Euphorbiaceae, native to South America, from Brazil, Paraguay and parts of the Andes. Although a perennial plant, cassava is extensively cultivated in tropical and subtropical regions as an annual crop for its edible starchy tuberous root. Cassava is predominantly consumed in boiled form, but substantial quantities are processed to extract cassava starch, called tapioca, which is used for food, animal feed, and industrial purposes. The Brazilian , and the related ''garri'' of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it (and roasting in the case of both and ''garri''). Cassava is the third-largest source of carbohydrates in food in the tropics, after rice and maize, making it an important staple food, staple; more than 500 million pe ...

Tapioca
Tapioca (; ) is a starch extracted from the tubers of the cassava plant (''Manihot esculenta,'' also known as manioc), a species native to the North Region, Brazil, North and Northeast Region, Brazil, Northeast regions of Brazil, but which has now spread throughout parts of the world such as West Africa and Southeast Asia. It is a perennial shrub adapted to the hot conditions of tropical lowlands. Cassava copes better with poor soils than many other food plants. Tapioca is a staple food for millions of people in tropical countries. It provides only carbohydrate food value, and is low in protein, vitamins, and Mineral (nutrient), minerals. In other countries, it is used as a thickening agent in various manufactured foods. Etymology ''Tapioca'' is derived from the word ''tipi'óka'', its name in the Tupi–Guarani languages, Tupi language spoken by natives when the Portuguese first arrived in the Northeast Region of Brazil around 1500. This Tupi word is translated as 'sedimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanide Poisoning
Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. Early symptoms include headache, dizziness, fast heart rate, shortness of breath, and vomiting. This phase may then be followed by seizures, slow heart rate, low blood pressure, loss of consciousness, and cardiac arrest. Onset of symptoms usually occurs within a few minutes. Some survivors have long-term neurological problems. Toxic cyanide-containing compounds include hydrogen cyanide gas and a number of cyanide salts, such as potassium cyanide. Poisoning is relatively common following breathing in smoke from a house fire. Other potential routes of exposure include workplaces involved in metal polishing, certain insecticides, the medication sodium nitroprusside, and certain seeds such as those of apples and apricots. Liquid forms of cyanide can be absorbed through the skin. Cyanide ions interfere with cellular respiration, resulting in the body's tissues being unable to use ...

Guarani Language
Guarani (Avañe'ẽ), also called Paraguayan Guarani, is a language of South America that belongs to the Tupi–Guarani branch of the Tupian languages, Tupian language family. It is one of the two official languages of Paraguay (along with Spanish language, Spanish), where it is spoken by the majority of the population, and where half of the rural population are monolingual speakers of the language. Variants of the language are spoken by communities in neighboring countries including parts of northeastern Argentina, southeastern Bolivia and southwestern Brazil. It is a second official language of the Provinces of Argentina, Argentine province of Corrientes Province, Corrientes since 2004 and in the Municipalities of Brazil, Brazilian city of Tacuru since 2010. Guarani is also one of the three official languages of Mercosur, alongside Spanish and Portuguese language, Portuguese.

Starch
Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diets, and is contained in large amounts in staple foods such as wheat, potatoes, maize (corn), rice, and cassava (manioc). Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or Alcohol (chemistry), alcohol. It consists of two types of molecules: the linear and helix, helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight. Glycogen, the energy reserve of animals, is a more highly branched version of amylopectin. In industry, starch is often converted into sugars, for example by malting. These sugars may be fermentation, fermented to produce ethanol in the manufacture of beer, whisky and biofuel. In addition, sugars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanide
In chemistry, cyanide () is an inorganic chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. Ionic cyanides contain the cyanide anion . This anion is extremely poisonous. Soluble cyanide salts such as sodium cyanide (NaCN), potassium cyanide (KCN) and tetraethylammonium cyanide () are highly toxic. Covalent cyanides contain the group, and are usually called nitriles if the group is linked by a single covalent bond to carbon atom. For example, in acetonitrile , the cyanide group is bonded to methyl . In tetracyanomethane , four cyano groups are bonded to carbon. Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus toxic. The cyano group may be covalently bonded to atoms different than carbon, e.g., in cyanogen azide , phosphorus tricyanide and trimethylsilyl cyanide . Hydrogen cyanide, or , is a highly volatile toxic liquid tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Illustration
Botanical illustration is the art of depicting the form, color, and details of plant species. They are generally meant to be scientifically descriptive about subjects depicted and are often found printed alongside a botanical description in books, magazines, and other media. Some are sold as artworks. Often composed by a botanical illustrator in consultation with a scientific author, their creation requires an understanding of plant morphology and access to specimens and references. Many illustrations are in watercolour, but may also be in oils, ink, or pencil, or a combination of these and other media. The image may be life-size or not, though at times a Scale (ratio), scale is shown, and may show the life cycle and/or habitat of the plant and its neighbors, the upper and reverse sides of leaves, and details of flowers, bud, seed and root system. The fragility of dried or otherwise preserved specimens, and restrictions or impracticalities of transport, saw illustrations used ...

Drought-tolerant
In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions'','' surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like Maize, corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. From an evolutionary perspective, the type of mycorrhizal associations formed in the roots of plants can determine how fast plants can adapt to drought. The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time. Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline), Reactive oxygen species, ROS-scavengi ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taíno
The Taíno are the Indigenous peoples of the Caribbean, Indigenous peoples of the Greater Antilles and surrounding islands. At the time of European contact in the late 15th century, they were the principal inhabitants of most of what is now The Bahamas, Cuba, the Dominican Republic, Haiti, Jamaica, Puerto Rico, and the northern Lesser Antilles. The Lucayan people, Lucayan branch of the Taíno were the first New World peoples encountered by Christopher Columbus, in the Lucayan Archipelago, Bahama Archipelago on October 12, 1492. The Taíno historically spoke an Arawakan languages, Arawakan language. Granberry and Vescelius (2004) recognized two varieties of the Taino language: "Classical Taino", spoken in Puerto Rico and most of Hispaniola, and "Ciboney Taino", spoken in the Bahamas, most of Cuba, western Hispaniola, and Jamaica. They lived in agricultural societies ruled by caciques with fixed settlements and a Matrilineality, matrilineal system of kinship and inheritance. Taíno ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...
