Taproot (band), Taproot
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious- or fibrous-root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries—for example, ''Welwitschia''. Description Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most often replaced later in the plant's development by a fibrous root system. ...

Root Systems
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Types of Roots (major rooting system) Plants exhibit two main root system types: ''taproot'' and ''fibrous'', with variations like adventitious, aerial, and buttress roots, each serving specific functions. Taproot System Characterized by a single, main root growing vertically downward, with smaller lateral roots branching off. Examples. Dandelions, carrots, and many dicot plants. Fibrous RootSystem Consists of a network of thin, branching roots that spread out from the base of the stem, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burdock
''Arctium'' is a genus of biennial plants commonly known as burdock, family Asteraceae. Native to Europe and Asia, several species have been widely introduced worldwide. Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of the hook and loop fastener. Description Plants of the genus ''Arctium'' have dark green leaves that can grow up to long. They are generally large, coarse, and ovate, with the lower ones being heart-shaped. They are woolly underneath. The leafstalks are generally hollow. ''Arctium'' species generally flower from July through October. Burdock flowers provide essential pollen and nectar for honeybees around August, when clover is on the wane and before the goldenrod starts to bloom. Burdock's clinging properties make it an excellent mechanism for seed dispersal. Taxonomy A large number of species have been placed in genus ''Arctium'' at one time or another, but most of them are now class ...

Quercus Kelloggii
''Quercus kelloggii'', the California black oak or Kellogg oak, is an oak in the red oak section (genus ''Quercus'', section ''Lobatae'', series ''Agrifoliae'') native to western North America. Description ''Quercus kelloggii'' grows from one to several vertical roots which penetrate to bedrock, with large, laterally spreading roots extending off from vertical ones. It also has a number of surface roots. It can reproduce vegetatively with new growth sprouting from the root crown after the tree is top-killed by wildfire, logging, frost, or other events. While individual trees generally have a lifespan between 100 and 200 years, California black oak can live up to 500 years. The tree typically grows from in height and from in diameter. Large trees may exceed in height and diameter, with the record holder measuring tall and thick (in the Siskiyou National Forest in Oregon). The species also grows in shrubby scrub-oak form on poor sites. In open areas, the crown is bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. ''World Flora Online'' accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, and ''Plants of the World Online'' 126 species-rank taxa (113 species and 13 nothospecies), making it the largest genus among the conifers. The highest species diversity of pines is found in Mexico. Pines are widely species distribution, distributed in the Northern Hemisphere; they occupy large areas of boreal forest, but are found in many habitats, including the Mediterranean Basin, and dry tropical forests in southeast Asia and Central America. Wood from pine trees is one of the most extensively used types of timber, and some pines are widely used as Christmas trees. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reachin ...

Asclepias Syriaca
''Asclepias syriaca'', commonly called common milkweed, butterfly flower, silkweed, silky swallow-wort, and Virginia silkweed, is a species of flowering plant. It is native to southern Canada and much of the United States east of the Rocky Mountains, excluding the drier parts of the prairies. It is in the genus ''Asclepias'', the milkweeds. It grows in sandy soils as well as other kinds of soils in sunny areas. Description ''A. syriaca'' is a clonal perennial forb growing up to tall. Individual plants grow from propagative roots. All parts of common milkweed plants produce a white latex when cut. The simple leaves are opposite, sometimes whorled; broadly ovate-lanceolate. They grow to long and broad, usually with entire, undulate margins and reddish main veins. They have very short petioles and velvety undersides. The highly fragrant, nectariferous flowers vary from white (rarely) through pinkish and purplish and occur in umbellate cymes. Individual flowers are about i ...

Turnip
The turnip or white turnip ('' Brassica rapa'' subsp. ''rapa'') is a root vegetable commonly grown in temperate climates worldwide for its white, fleshy taproot. Small, tender varieties are grown for human consumption, while larger varieties are grown as feed for livestock. The name ''turnip'' used in many regions may also be used to refer to rutabaga (or ''neep'' or ''swede''), which is a different but related vegetable. Etymology The origin of the word ''turnip'' is uncertain, though it is hypothesised that it could be a compound of ''turn'' as in turned/rounded on a lathe and ''neep'', derived from Latin ''napus'', the word for the plant. According to An Universal Etymological English Dictionary, ''turn'' refers to "round ''napus'' to distinguish it from the napi, which were generally long". Description The most common type of turnip is mostly white-skinned, apart from the upper , which protrude above the ground and are purple or red or greenish where the sun has h ...

Radish
The radish (''Raphanus sativus'') is a flowering plant in the mustard family, Brassicaceae. Its large taproot is commonly used as a root vegetable, although the entire plant is edible and its leaves are sometimes used as a leaf vegetable. Originally domesticated in Asia, radishes are now grown and consumed globally. The radish is sometimes considered to form a species complex with the wild radish, and instead given the trinomial name ''Raphanus raphanistrum'' subsp. ''sativus''. Radishes are often used raw as a crunchy salad vegetable with a pungent, slightly spicy flavor, varying in intensity depending on its growing environment. There are numerous varieties varying in size, flavor, color, and length of time they take to mature. Radishes owe their sharp flavor to the various chemical compounds produced by the plants, including glucosinolate, myrosinase, and isothiocyanate. They are sometimes grown as companion plants and suffer from few pests and diseases. They germinate q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppy Mallow

Parsnip
The parsnip (''Pastinaca sativa'') is a root vegetable closely related to carrot and parsley, all belonging to the flowering plant family Apiaceae. It is a biennial plant usually grown as an annual. Its long taproot has cream-colored skin and flesh, and, left in the ground to mature, becomes sweeter in flavor after winter frosts. In its first growing season, the plant has a rosette of pinnate, mid-green leaves. If unharvested, it produces a flowering stem topped by an umbel of small yellow flowers in its second growing season, later producing pale brown, flat, winged seeds. By this time, the stem has become woody, and the taproot inedible. Precautions should be taken when handling the stems and foliage, as parsnip sap can cause a skin rash or even blindness if exposed to sunlight after handling. The parsnip is native to Eurasia; it has been used as a vegetable since antiquity and was cultivated by the Romans, although some confusion exists between parsnips and carrots i ...

Parsley
Parsley, or garden parsley (''Petroselinum crispum''), is a species of flowering plant in the family Apiaceae that is native to Greece, Morocco and the former Yugoslavia. It has been introduced and naturalisation (biology), naturalized in Europe and elsewhere in the world with suitable climates, and is widely cultivated as an herb and a vegetable. It is believed to have been originally grown in Sardinia, and was cultivated in around the 3rd century BC. Linnaeus stated its wild habitat to be Sardinia, whence it was brought to England and apparently first cultivated in Britain in 1548, though literary evidence suggests parsley was used in England in the Middle Ages as early as the Anglo-Saxon period. Parsley is widely used in European cuisine, European, Middle Eastern cuisine, Middle Eastern, and American cuisine. Curly-leaf parsley is often used as a garnish (food), garnish. In Central European cuisine, central Europe, Eastern European cuisine, eastern Europe, and southern Eur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
