Avicenniaceae
''Avicennia'' is a genus of flowering plants currently placed in the bear's breeches family, Acanthaceae. It contains mangrove trees, which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots. They are also commonly known as ''api api'', which in the Malay language means "fires", a reference to the fact that fireflies often congregate on these trees. Species of ''Avicennia'' occur worldwide south of the Tropic of Cancer. The taxonomic placement of ''Avicennia'' is contentious. In some classifications, it has been placed in the family Verbenaceae, but more recently has been placed by some botanists in the monogeneric family Avicenniaceae. Recent phylogenetic studies have suggested that ''Avicennia'' is derived from within Acanthaceae, and the genus is included in that family in the Angiosperm Phylogeny Group system. Designation of species is made difficult by the great variations in form of '' Avicennia mari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acanthaceae
Acanthaceae () is a Family (biology), family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are Tropics, tropical Herbaceous plant, herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every Habitat (ecology), habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests. Description Plants in this family have simple, opposite, decussated leaf, leaves with entire (or sometimes toothed, lobed, or spiny) margins, and without stipules. The leaves may contain cystoliths, calcium carbonate concretions, seen as streaks on the surface. The flowers are perfect, Floral symmetry, zygomorphic to nearly Floral symmetry, actinomorphic, and arran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avicennia Marina
''Avicennia marina'', commonly known as grey mangrove or white mangrove, is a species of mangrove tree classified in the plant family Acanthaceae (formerly in the Verbenaceae or Avicenniaceae). As with other mangroves, it occurs in the intertidal zones of estuarine areas. Description Grey mangroves grow as a shrub or tree to a height of , or up to in tropical regions. The habit is a gnarled arrangement of multiple branches. It has smooth light-grey bark made up of thin, stiff, brittle flakes. This may be whitish, a characteristic described in the common name. The leaves are thick, long, a bright, glossy green on the upper surface, and silvery-white, or grey, with very small matted hairs on the surface below. As with other ''Avicennia'' species, it has aerial roots (pneumatophores), which grow to a height of about , and a diameter of . These allow the plant to absorb oxygen, which is deficient in its habitat. These roots also anchor the plant during the frequent inundatio ...

Verbenaceae
The Verbenaceae ( ), the verbena family or vervain family, is a family of mainly tropical flowering plants. It contains trees, shrubs, and herbs notable for heads, spikes, or clusters of small flowers, many of which have an aromatic smell. The family Verbenaceae includes 32 genera and 800 species. Phylogenetic studies have shown that numerous genera traditionally classified in Verbenaceae belong instead in Lamiaceae. The mangrove genus ''Avicennia'', sometimes placed in the Verbenaceae or in its own family, Avicenniaceae, has been placed in the Acanthaceae. Economically important Verbenaceae include: * Lemon verbena (''Aloysia triphylla''), grown for aroma or flavoring * Verbenas or vervains (''Verbena''), some used in herbalism, others grown in gardens Taxonomy Tribes and genera in the family and their estimated species numbers: Casselieae (Schauer) Tronc. * ''Casselia'' Nees & Mart. - 6 species * ''Parodianthus'' Tronc. - 2 species * ''Tamonea'' Aubl. - 6 species C ...

Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avicennia Germinans
''Avicennia germinans'', the black mangrove, is a shrub or small tree growing up to 12 meters (39 feet) in the acanthus family, Acanthaceae. It grows in tropical and subtropical regions of the Americas, on both the Atlantic and Pacific Coasts, and on the Atlantic Coast of tropical Africa, where it thrives on the sandy and muddy shores where seawater reaches. It is common throughout coastal areas of Texas and Florida, and ranges as far north as southern Louisiana and northern Florida in the United States. Like many other mangrove species, it reproduces by vivipary. Seeds are encased in a fruit, which reveals the germinated seedling when it falls into the water. Unlike other mangrove species, it does not grow on prop roots, but possesses pneumatophores that allow its roots to breathe even when submerged. It is a hardy species and expels absorbed salt mainly from its leathery leaves. The name "black mangrove" refers to the color of the trunk and heartwood. The leaves oft ...

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation. In agriculture and horticulture * Cellulose substrate * Expanded clay aggregate (LECA) * Rock wool * Potting soil * Soil In animal biotechnology Requirements for animal cell and tissue culture Requirements for animal cell and tissue culture are the same as described for plant cell, tissue and organ culture (In Vitro Culture Techniques: The Biotechnological Principles). Desirable requirements are (i) air conditioning of a room, (ii) hot room with temperature recorder, (iii) microsc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persian People
Persians ( ), or the Persian people (), are an Iranian peoples, Iranian ethnic group from West Asia that came from an earlier group called the Proto-Iranians, which likely split from the Indo-Iranians in 1800 BCE from either Afghanistan or Central Asia. They are indigenous to the Iranian plateau and comprise the majority of the population of Iran.Iran Census Results 2016 United Nations Alongside having a Culture of Iran, common cultural system, they are native speakers of the Persian language and of the Western Iranian languages that are closely related to it.

Islamic Medicine
In the history of medicine, "Islamic medicine", also known as "Arabian medicine" is the science of medicine developed in the Middle East, and usually written in Arabic, the ''lingua franca'' of Islamic civilization. Islamic medicine adopted, systematized and developed the medical knowledge of classical antiquity, including the major traditions of Hippocrates, Galen and Dioscorides. During the post-classical era, Middle Eastern medicine was the most advanced in the world, integrating concepts of Modern Greek, Roman, Mesopotamian and Persian medicine as well as the ancient Indian tradition of Ayurveda, while making numerous advances and innovations. Islamic medicine, along with knowledge of classical medicine, was later adopted in the medieval medicine of Western Europe, after European physicians became familiar with Islamic medical authors during the Renaissance of the 12th century. Medieval Islamic physicians largely retained their authority until the rise of medicine as a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avicenna
Ibn Sina ( – 22 June 1037), commonly known in the West as Avicenna ( ), was a preeminent philosopher and physician of the Muslim world, flourishing during the Islamic Golden Age, serving in the courts of various Iranian peoples, Iranian rulers. He is often described as the father of early modern medicine. His philosophy was of the Peripatetic school derived from Aristotelianism. His most famous works are ''The Book of Healing'', a philosophical and scientific encyclopedia, and ''The Canon of Medicine'', a medical encyclopedia which became a standard medical text at many medieval European University, universities and remained in use as late as 1650. Besides philosophy and medicine, Avicenna's corpus includes writings on Astronomy in medieval Islam, astronomy, Alchemy and chemistry in medieval Islam, alchemy, Geography and cartography in medieval Islam, geography and geology, Psychology in medieval Islam, psychology, Islamic theology, Logic in Islamic philosophy, logic, Mat ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Pneumatophore
Aerial roots are roots growing above the ground. They are often adventitious, i.e. formed from nonroot tissue. They are found in diverse plant species, including epiphytes such as orchids (''Orchidaceae''), tropical coastal swamp trees such as mangroves, banyan figs ('' Ficus subg. Urostigma''), the warm-temperate rainforest rata ('' Metrosideros robusta''), and pōhutukawa trees of New Zealand (''Metrosideros excelsa''). Vines such as common ivy ('' Hedera helix'') and poison ivy (''Toxicodendron radicans'') also have aerial roots. Types This plant organ that is found in so many diverse plant-families has different specializations that suit the plant-habitat. In general growth-form, they can be technically classed as '' negatively gravitropic'' (grows up and away from the ground) or ''positively gravitropic'' (grows down toward the ground). "Stranglers" (prop-root) Banyan trees are an example of a strangler fig that begins life as an epiphyte in the crown of another tr ...
