Hewittia (plant)
''Hewittia malabarica'' is a flowering plant in the monotypic genus ''Hewittia'' , belonging to the family Convolvulaceae and widespread throughout tropical Africa, Asia, and Polynesia. It is a climbing or prostrate perennial herb with slender stems and flowers that are pale yellow, cream, or white with a purple center, and large leaves that can be used as a cooked vegetable or used in folk medicine with the roots. The stems can be used to make ropes. Description ''Hewittia malabarica'' is close in form to some '' Convolvulus'' species. It is a twining,O. A. Leistner climbing or prostrate,G. J. H. Grubben and O.A. Denton herbaceous perennial plant. with a stem that is velvet-hairy or pubescent (covered in downy hairs) and slender that is up to long. These long stems can twin or climb into the surrounding vegetation, or they scramble over the ground where they occasionally form new roots at the nodes. The leaves are arranged alternately, with a petiole (leaf stalk) that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corolla (flower)
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and ''Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alternative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malabar Coast
The Malabar Coast is the southwestern coast of the Indian subcontinent. Geographically, it comprises the wettest regions of southern India, as the Western Ghats intercept the moisture-laden monsoon rains, especially on their westward-facing mountain slopes. The term is used to refer to the entire Indian coast from the western coast of Konkan to the tip of India at Kanyakumari. The peak of Anamudi, which is also the point of highest altitude in India outside the Himalayas, and Kuttanad, which is the point of least elevation in India, lie on the Malabar Coast. Kuttanad, also known as ''The Rice Bowl of Kerala'', has the lowest altitude in India, and is also one of the few places in the world where cultivation takes place below sea level. The region parallel to the Malabar Coast gently slopes from the eastern highland of Western Ghats ranges to the western coastal lowland. The moisture-laden winds of the Southwest monsoon, on reaching the southernmost point of the Indian Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phrenologist
Phrenology () is a pseudoscience which involves the measurement of bumps on the skull to predict mental traits.Wihe, J. V. (2002). "Science and Pseudoscience: A Primer in Critical Thinking." In ''Encyclopedia of Pseudoscience'', pp. 195–203. California: Skeptics Society.Hines, T. (2002). ''Pseudoscience and the Paranormal''. New York: Prometheus Books. p. 200 It is based on the concept that the brain is the organ of the mind, and that certain brain areas have localized, specific functions or modules. It was said that the brain was composed of different muscles, so those that were used more often were bigger, resulting in the different skull shapes. This led to the reasoning behind why everyone had bumps on the skull in different locations. The brain "muscles" not being used as frequently remained small and were therefore not present on the exterior of the skull. Although both of those ideas have a basis in reality, phrenology generalized beyond empirical knowledge in a way that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hewett Watson
Hewett Cottrell Watson (9 May 1804 – 27 July 1881) was a phrenologist, botanist and theory of evolution, evolutionary theorist. He was born in Firbeck, near Rotherham, Yorkshire, and died at Thames Ditton, Surrey. Biography Watson was the eldest son of Holland Watson, a Justice of the Peace and Mayor of Congleton in Cheshire, and his wife, Harriet Powell. His mother died when he was fifteen. He had seven older sisters and two younger brothers and his early life was overshadowed by a terrible relationship with his father, a reactionary conservative whose character Watson himself detailed in later years. As a teenager, Watson suffered a serious injury to his knee in a cricket match, and never recovered full movement in the joint again. Watson's mother had attempted to distract him from family tensions by sending him to work with the family's gardener, and it was after her death that his obsession with botany began. While training for the legal profession in Liverpool, Watson bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seeds
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general meaning that anteda ...

Anthers
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 ''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'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
