Plant
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 ...

Euphorbiaceae
Euphorbiaceae (), the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of Euphorbia, the type genus of the family. Most spurges, such as ''Euphorbia paralias'', are herbaceous plant, herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cactus, cacti because of convergent evolution. This family has a Cosmopolitan distribution, cosmopolitan global distribution. The greatest diversity of species is in the tropics; however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The Leaf, leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to trichome#Plant trichomes, hairs, glands, or spine (botany), spines, or in succulent specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Socotra
Socotra, locally known as Saqatri, is a Yemeni island in the Indian Ocean. Situated between the Guardafui Channel and the Arabian Sea, it lies near major shipping routes. Socotra is the largest of the six islands in the Socotra archipelago as it comprises around 95% of the landmass of the archipelago. It lies south of the Arabian Peninsula and east of the Horn of Africa. The inhabitants of the island are called Soqotri people, Socotrans, and they speak Arabic and Soqotri language, Soqotri. Socotra is home to a high number of unique species that are endemism, endemic to it. Up to a third of its plant life is unique. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth". The island measures in length and across at its widest. In 2008, Socotra was recognised as a UNESCO World Heritage Site. The island is under the control of the Southern Transitional Council (STC), a United Arab Emirates-backed, pro-Presidential Leadership Co ...

Yemen
Yemen, officially the Republic of Yemen, is a country in West Asia. Located in South Arabia, southern Arabia, it borders Saudi Arabia to Saudi Arabia–Yemen border, the north, Oman to Oman–Yemen border, the northeast, the south-eastern part of the Arabian Sea to the east, the Gulf of Aden to the south, and the Red Sea to the west, sharing maritime boundary, maritime borders with Djibouti, Eritrea, and Somalia across the Horn of Africa. Covering roughly 455,503 square kilometres (175,871 square miles), with a coastline of approximately , Yemen is the second largest country on the Arabian Peninsula. Sanaa is its constitutional capital and largest city. Yemen's estimated population is 34.7 million, mostly Arabs, Arab Muslims. It is a member of the Arab League, the United Nations, the Non-Aligned Movement and the Organisation of Islamic Cooperation. Owing to its geographic location, Yemen has been at the crossroads of many civilisations for over 7,000 years. In 1200 BCE, the Sab ...

Soqotri
Soqotri (; ) is a South Semitic language spoken by the Soqotri people on the island of Socotra and the two nearby islands of Abd al Kuri and Samhah, in the Socotra archipelago, in the Guardafui Channel. Soqotri is one of six languages that form a group called Modern South Arabian languages (MSAL). These additional languages include Mehri, Shehri, Bathari, Harsusi and Hobyot. All are spoken in different regions of Southern Arabia. Classification Soqotri is often mistaken as a variety of Arabic but is typically classified as an Afro-Asiatic, Semitic, South Semitic and South Arabian language. Scholars believe there are no longer any grounds for associating the Modern South Arabian languages so directly with Arabic. They consider these dialects to be not Arabic, but Semitic languages in their own right. Dialects The Soqotri dialectology is very rich, especially considering the surface of the island and number of inhabitants. Soqotri speakers live on their islands, but rarely ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Jatropha
''Jatropha'' is a genus of flowering plants in the spurge family, Euphorbiaceae. The name is derived from the Greek words ἰατρός (''iatros''), meaning "physician", and τροφή (''trophe''), meaning "nutrition", hence the common name physic nut. Another common name is nettlespurge. It contains approximately 180 species of succulent plants, shrubs and trees (some are deciduous, like '' Jatropha curcas''). Most of these are native to the Americas, with 66 species found in the Old World. Plants produce separate male and female flowers. As with many members of the family Euphorbiaceae, ''Jatropha'' contains compounds that are highly toxic. ''Jatropha'' species have traditionally been used in basketmaking, tanning and dye production. In the 2000s, one species, '' Jatropha curcas'', generated interest as an oil crop for biodiesel production and also medicinal importance when used as lamp oil; native Mexicans in the Veracruz area developed by selective breeding a ''Jatropha cur ...

Least Concern Plants
The degrees of comparison of adjectives and adverbs are the various forms taken by adjectives and adverbs when used to compare two entities (comparative degree), three or more entities (superlative degree), or when not comparing entities (positive degree) in terms of a certain property or way of doing something. The usual degrees of comparison are the ''positive'', which denotes a certain property or a certain way of doing something without comparing (as with the English words ''big'' and ''fully''); the ''comparative degree'', which indicates ''greater'' degree (e.g. ''bigger'' and ''more fully'' omparative of superiorityor ''as big'' and ''as fully'' omparative of equalityor ''less big'' and ''less fully'' omparative of inferiority; and the ''superlative'', which indicates ''greatest'' degree (e.g. ''biggest'' and ''most fully'' uperlative of superiorityor ''least big'' and ''least fully'' uperlative of inferiority.
