Plant morphology or phytomorphology is the study of the physical form and external structure of plants. This is usually considered distinct from plant anatomy, which is the study of the internal structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants.
Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarity of plan and origin." There are four major areas of investigation in plant morphology, and each overlaps with another field of the biological sciences.
First of all, morphology is comparative, meaning that the morphologist examines structures in many different plants of the same or different species, then draws comparisons and formulates ideas about similarities. When structures in different species are believed to exist and develop as a result of common, inherited genetic pathways, those structures are termed homologous. For example, the leaves of pine, oak, and cabbage all look very different, but share certain basic structures and arrangement of parts. The homology of leaves is an easy conclusion to make. The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.
The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with about 350,000 species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word (angeion-, "case" or "casing", and sperma, "seed") meaning "enclosed seeds", after the enclosed condition of the seeds.
The ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago (mya), and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, and replaced conifers as the dominant trees during 100 to 60 mya.
Morphology, from the Greek and meaning "study of shape", may mean:
Gamma radiation (sometimes called gamma ray), denoted by the lower-case Greek letter gamma (γ), is extremely high-frequency electromagnetic radiation and therefore consists of high-energy photons. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays. Rutherford had previously discovered two other types of radioactive decay, which he named alpha and beta rays.
Gamma rays are ionizing radiation, and are thus biologically hazardous. Decay of an atomic nucleus from a high energy state to a lower energy state, a process called gamma decay, produces gamma radiation. This is what Villard had observed.
Natural sources of gamma rays on Earth include gamma decay of radionuclides and secondary radiation from atmospheric interactions with cosmic ray particles. Rare terrestrial natural sources produce gamma rays that are not of a nuclear origin, such as lightning strikes and terrestrial gamma-ray flashes. Additionally, gamma rays are produced by a number of astronomical processes in which very high-energy electrons are produced, that in turn cause secondary gamma rays via bremsstrahlung, inverse Compton scattering, and synchrotron radiation. However, a large fraction of such astronomical gamma rays are screened by Earth's atmosphere and can only be detected by spacecraft. Gamma rays are produced by nuclear fusion in stars including the Sun (such as the CNO cycle), but are absorbed or inelastically scattered by the stellar material before escaping and are not observable from Earth.

They may be borne directly on a main stem axis or rachis (sessile) or on a slender stalk or stem called a pedicel. They usually consist of four whorls of parts that develop in the following series, from the outer whorl to the inner: sepals, petals, stamens, and carpels. These whorls of parts may develop in discrete cycles, or be more or less continuous and spirally arranged. If all four whorls of floral parts are present, the flower is complete; if one or more whorls is missing, the flower is incomplete...

Morphological adjustment among flowers and their pollinators is an essential component of life in ecosystems. This leads to one of the most beautiful mutualisms in nature: pollination by animals. Flowers provide energetic nectar to visitors, which in return carry the pollen from one flower to another, helping the plant in reproduction. However, there are floral visitors whose body does not match the morphology of the flower. Unable to access the precious nectar, the potential pollinators turn in to robbers and make a hole in the corolla tube where they can extract the nectar. This usually damages the flower, but sometimes a clumsy robber can inadvertently pollinate the flower. This video shows that when we explore nature with an open eye, we often realize the many “human” behaviours have b...
"Japanese Gamma Rays" by Grey Payday. Video art montage digitally composited using Final Cut Pro 7.0.3 and CoreMelt Complete V2. Edited in Arendal, Norway. The video tells the pestilential story of the Fukushima Disaster, from the construction of the Fukushima Daiichi Nuclear Power Plant in 1967, the 2011 earthquake and subsequent tsunami, the government's malpractice of the disaster and the inadvertent acts of plant operator, TEPCO. The video revisits some imagery of Emperor Shōwa during the Second World War, and artworks of civilians depicted during the nuclear bombing of Hiroshima in 1945. The affects of the disaster, charged by harmful gamma rays, will continue to devastate the nation in the form of poisoned land and sea, and diseases including cancer and morphological irregularities ...

"If for monotheism, earth is not a planet but rather a religious object, it is because, as Qutb emphasizes, the earth itself moves towards the Divine by submitting itself to the ‘exterior’ Will of Allah; or in other words, the earth is a part and property of Islam, that is to say, the religion of utter submission to Allah. Islam does not perceive oil merely as a motor-grease -- in the way Capitalism identifies it -- but predominantly as a lubricant current or a tellurian flux upon which everything is mobilized in the direction of submission to a desert where no idol can be erected and all elevations must be burned down – that is, the Kingdom of...
DNA extraction is one of the critical stages in the acquisition of DNA barcodes. We have developed a set of “Mix and Match” protocols allowing the extraction of DNA from various organisms including fungi and plants. These protocols are compatible with automation and deliver high quality DNA for only a fraction of the cost associated with the use of commercial kits. In addition, the voucher recovery step aids in preserving the morphology of small specimens for future reference. The same protocols can be easily down-scaled to a tube format for forensic applications and low throughput labs. Please also see the video featured at the end of this webinar, showing "Glass Fiber Automated DNA Extraction" at full motion and in higher resolution.

Genetic Entropy - The Stark Reality After much reading, research, and debate with evolutionists, I find the principle of Genetic Entropy (loss of functional information) to be the true principle guiding all 'beneficial' biological adaptations which directly contradicts unguided neo-Darwinian evolution. As well, unlike Darwinian evolution which can claim no primary principles in science to rest its claim on for the generation of functional information, Genetic Entropy can rest its foundation in science directly on the twin pillars of the Second Law of Thermodynamics and on the Law of Conservation Of Information(LCI; Dembski,Marks)(Null Hypothesis;Abel). The first phase of Genetic Entropy, any life-form will go through, holds all sub-speciation adaptations away from a parent species, which ...
SWS 2010 annual meeting. Symposium: "Wetland Development and Wetland Restoration: Looking at History and Planning the Future" Presentation #4 by Gary J. Pierce of Froghome Environmental, LLC. "WETLAND DEVELOPMENT TODAY" Abstract: Five points summarize the state of the art in modern wetland development for mitigation and other purposes. These are: 1.Planning based on specific measurable and achievable goals that are an expression of desired functions, and preparing plans based on structural components that support the desired functions. 2.Preparation of plans based on two conceptual models. The first involves determining the applicable hydrology, geology, and morphology of the planned wetland according to the selected landscape position. A second model is to account for the varia...
Author:Marko Jovanović mail: markovimejlovi@gmail.com portfolio: www.architizer.com/en_us/people/profile/marko_jovanovic/ Micro-locations will try to maintain practical dialogue with users eager to socialize, or to spend some time in solitude or just to play. With small dimensions, made of warm and natural materials, protected from unwanted environmental effects, these “inner spaces” will give a qualitative way of extended housing. One of the most important features of the site is its microclimate, which is defined by the climatic variations of the regional climate. To these exceptions is due to the difference of location in relation to altitude, slope and its orientation, configuration and proximity of large water surfaces. The position of the complex should be located studying the his...
