Symplocos Paniculata
''Symplocos paniculata'', called Asiatic sweetleaf or sapphire-berry, is a species of tree in the family Symplocaceae. It is native to all of eastern Asia and was introduced to the United States in around 1871. It is a tree reaching in favorable conditions, though it is often more shrub-like, and is used as an ornamental due to its visually striking blue fruit from which it derives its common name. Description The intensely blue fruit of the tree are relatively short-lived, as the fleshy berries are quickly eaten by birds. The foliage of the tree is neat and the flowers are often fragrant. The leaves have short petioles and vary in their ovoid shape, measuring up to in length and half as wide. The leaves bear some trichomes above and are far more pubescent on their veins beneath. The species blooms in early summer after leaves have developed. These whitish blooms are formed in lateral clusters up to long, with each hermaphroditic flower bearing five petals and thirty stamens ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermaphroditic
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species (called trioecy); these three systems are so ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Bangladeshi
Bangladeshis ( bn, বাংলাদেশী ) are the citizens of Bangladesh, a South Asian country centered on the transnational historical region of Bengal along the eponymous bay. Bangladeshi citizenship was formed in 1971, when the permanent residents of the former East Pakistan were transformed into citizens of a new republic. Bangladesh is the world's eighth most populous nation. The vast majority of Bangladeshis are ethnolingustically Bengalis, an Indo-Aryan people. The population of Bangladesh is concentrated in the fertile Bengal delta, which has been the center of urban and agrarian civilizations for millennia. The country's highlands, including the Chittagong Hill Tracts and parts of the Sylhet Division, are home to various tribal minorities. Bengali Muslims are the predominant ethnoreligious group of Bangladesh with a population of 150.36 million, which makes up 91.04% of the country's population as of 2022. The minority Bengali Hindu population made up app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antidiarrhoeal
An anti-diarrhoeal drug (or anti-diarrheal drug in American English) is any medication which provides symptomatic relief for diarrhoea. Types * Electrolyte solutions, while not true antidiarrhoeals, are used to replace lost fluids and salts in acute cases. * Bulking agents like methylcellulose, guar gum or plant fibre (bran, sterculia, isabgol, etc.) are used for diarrhoea in functional bowel disease and to control ileostomy output. * Absorbents absorb toxic substances that cause infective diarrhoea, methylcellulose is an absorbent. * Anti-inflammatory compounds such as bismuth subsalicylate. * Anticholinergics reduce intestinal movement and are effective against both diarrhoea and accompanying cramping. * Opioids' classical use besides pain relief is as an anti-diarrhoeal drug. Opioids have agonist actions on the intestinal opioid receptors, which when activated cause constipation. Drugs such as morphine or codeine can be used to relieve diarrhoea this way. A notable opioid fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cromakalim
Cromakalim (INN) is a potassium channel-opening vasodilator. The active isomer is levcromakalim. It acts on ATP-sensitive potassium channels and so causes membrane hyperpolarization. It can be used to treat hypertension as it will relax vascular smooth muscle to lower blood pressure. Hyperpolarisation of smooth muscle cell membranes pulls their membrane potential away from the threshold, so making it more difficult to excite them and thereby cause relaxation. Synthesis Reaction of 4-cyanophenol (4-Hydroxybenzonitrile) with 2-hydroxy-2-methyl-3-butyne under PTC probably proceeds to initial formation of a propargyl carbocation. The course of the reaction can be envisaged by assuming that this then attacks the aromatic ring; the resulting allylic cation can then capture the adjacent phenol oxygen and thus form the observed product (3). Treatment of that product with aqueous NBS leads to the addition of the elements of hypobromous acid and formation of the bromohydrin (4) as ...

Plants Described In 1867
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
