Sapindaceae
The Sapindaceae are a family (biology), family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1,858 accepted species. Examples include Aesculus, horse chestnut, maples, ackee and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are Glossary of botanical terms#laticiferous, laticiferous, i.e. they contain latex, a milky sap, and many contain mildly Toxicity, toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are ''Serjania'', ''Paullinia'', ''Allophylus'' and ''Maple, Acer''. Description Plants of this family have a variety of habits, from trees to herbaceous plants to lianas. The leaves of the tropical genera are usually spirally alternate, while those of the temperate maples (''Maple, Acer), Aesculus'', and a few other genera are opposite. They are most often leaf shape, pinnately compound, but a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ficus Religiosa
''Ficus religiosa'' or sacred fig is a species of fig native to the Indian subcontinent and Indochina that belongs to Moraceae, the fig or mulberry family. It is also known as the bodhi tree, bo tree, peepul tree, peepal tree, pipala tree or ashvattha tree (in India and Nepal). The sacred fig is considered to have a religious significance in four major religions that originated on the Indian subcontinent: Hinduism, Buddhism, Sikhism and Jainism. Hindu and Jain ascetics consider the species to be sacred and often meditate under it. Gautama Buddha is believed to have attained enlightenment under a tree of this species. The sacred fig is the state tree of the Indian states of Odisha, Bihar and Haryana.

Melanoma
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). In very rare cases melanoma can also happen in the lung which is known as primary pulmonary melanoma and only happens in 0.01% of primary lung tumors. In women, melanomas most commonly occur on the legs; while in men, on the back. Melanoma is frequently referred to as malignant melanoma. However, the medical community stresses that there is no such thing as a 'benign melanoma' and recommends that the term 'malignant melanoma' should be avoided as redundant. About 25% of melanomas develop from nevus, moles. Changes in a mole that can indicate melanoma include increaseespecially rapid increasein size, irregular edges, change in color, itchiness, or nevus#Classification, skin breakdown. The primary cause of melanoma is ultraviolet light (UV) exposure in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cervical Cancer
Cervical cancer is a cancer arising from the cervix or in any layer of the wall of the cervix. It is due to the abnormal growth of cells that can invade or spread to other parts of the body. Early on, typically no symptoms are seen. Later symptoms may include abnormal vaginal bleeding, pelvic pain or pain during sexual intercourse. While bleeding after sex may not be serious, it may also indicate the presence of cervical cancer. Virtually all cervical cancer cases (99%) are linked to genital human papillomavirus infection (HPV); most who have had HPV infections, however, do not develop cervical cancer. HPV 16 and 18 strains are responsible for approximately 70% of cervical cancer cases globally and nearly 50% of high grade cervical pre-cancers. Minor risk factors include smoking, a weak immune system, birth control pills, starting sex at a young age, and having many sexual partners. Genetic factors also contribute to cervical cancer risk. Cervical cancer typically develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovary Cancer
Ovarian cancer is a cancerous tumor of an ovary. It may originate from the ovary itself or more commonly from communicating nearby structures such as fallopian tubes or the inner lining of the abdomen. The ovary is made up of three different cell types including epithelial cells, germ cells, and stromal cells. When these cells become abnormal, they have the ability to divide and form tumors. These cells can also invade or spread to other parts of the body. When this process begins, there may be no or only vague symptoms. Symptoms become more noticeable as the cancer progresses. These symptoms may include bloating, vaginal bleeding, pelvic pain, abdominal swelling, constipation, and loss of appetite, among others. Common areas to which the cancer may spread include the lining of the abdomen, lymph nodes, lungs, and liver. The risk of ovarian cancer increases with age. Most cases of ovarian cancer develop after menopause. It is also more common in women who have ovulated mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar Source
A nectar source is a flowering plant that produces nectar (plant), nectar as part of its reproductive strategy. These plants create nectar, which attract pollinating insects and sometimes other animals such as birds. Nectar source plants are important for beekeeping, as well as in agriculture and horticulture. Their use is particularly important for organic agriculture and organic horticulture, where they serve not only to attract pollinators for crops, but also provide habitat for beneficial insects and other animals that provide pest control. In gardens, nectar sources are often provided to attract butterflies and hummingbirds as well. For honey bees While many plants produce nectar, beekeepers prefer to place their hives near certain plants, for the qualities of the honey produced. Certain agricultural crops, such as clover and buckwheat, are used to make Monofloral honey, specific honeys, which often command a premium price. Some plants are avoided by some beekeepers (and ...

Reducing Sugar
A reducing sugar is any sugar that is capable of acting as a reducing agent. In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent. In such a reaction, the sugar becomes a carboxylic acid. All monosaccharides are reducing sugars, along with some disaccharides, some oligosaccharides, and some polysaccharides. The monosaccharides can be divided into two groups: the aldoses, which have an aldehyde group, and the ketoses, which have a ketone group. Ketoses must first tautomerize to aldoses before they can act as reducing sugars. The common dietary monosaccharides galactose, glucose and fructose are all reducing sugars. Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing. Nonreducing disaccharides like sucrose and trehalose have glycosidic bonds between their anomeric carbons and thus cannot convert to an open-chain form with an ...

Aesculus
The genus ''Aesculus'' ( or ), with notable species including buckeye and horse chestnut, comprises 13–19 species of flowering plants in the family Sapindaceae. They are trees and shrubs native plant, native to the temperateness, temperate Northern Hemisphere, with six species native to North America and seven to 13 species native to Eurasia. Several Hybrid (biology), hybrids occur. ''Aesculus'' exhibits a classical Arcto-Tertiary Geoflora, Arcto-Tertiary distribution. Ungnadia, Mexican buckeye seedpods resemble the ''Aesculus'' seedpods, but belong to a different genus. Carl Linnaeus named the genus ''Aesculus'' after the Roman name for an edible acorn. Common names for these trees include "buckeye" and "horse chestnut", though they are not in the same order as the true chestnuts, ''Castanea'' in the Fagales. Some are also called white chestnut or red chestnut. In Britain, they are sometimes called conker trees because of their link to the game of conkers, played with t ...

Capsule (fruit)
In botany, a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms ( flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpellary) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of '' Adansonia digitata'', '' Alphitonia'', and '' Merciera''. Capsules are often ...

Panicle
In botany, a panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses, such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' co ...

Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
