Erica (plant)
''Erica'' is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus ''Calluna'' was formerly included in ''Erica'' – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. ''Erica'' is sometimes referred to as "winter (or spring) heather" to distinguish it from ''Calluna'' "summer (or autumn) heather". Etymology The Latin word ''erica'' means "heath" or "broom". It is believed that Pliny adapted ''erica'' from Ancient Greek ἐρείκη. The expected Anglo-Latin pronunciation, , may be given in dictionaries (''OED'': "Erica"), but is more commonly heard. Description Most of the species of ''Erica'' are small shrubs from high, though some are taller; the tallest are '' E. arborea'' (tree heath) and '' E. scoparia'' (besom heath), both of which can reach up ...

Erica Carnea
''Erica carnea'', the winter heath, winter-flowering heather, spring heath or alpine heath, is a species of flowering plant in the family Ericaceae, native to mountainous areas of central, eastern and southern Europe, where it grows in coniferous woodlands or stony slopes. Description It is a low-growing, spreading subshrub reaching tall, with evergreen needle-like leaves long, borne in whorls of four. The flowers are produced in racemes in late winter to early spring, often starting to flower while the plant is still covered in snow; the individual flower is a slender bell-shape, long, dark reddish-pink, rarely white. Names The first published name for the species is ''Erica herbacea''; however, the name ''E. carnea'' (published three pages later in the same book) is so widely used, and the earlier name so little used, that a formal proposal to conserve the name ''E. carnea'' over ''E. herbacea'' was accepted by the International Botanical Congress in 1999.

Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

Erica Abietina
''Erica abietina'' is a species of erica that is endemic to the Cape Peninsula of the Western Cape, South Africa. ''E. abietina'' includes four subspecies with often highly restricted distributions and distinctive flower colours. Previous delimitation of the species has included a further three subspecies which proved to be more distantly related to Cape Peninsula endemic ''E. abietina'' subspecies and are now classified under '' Erica grandiflora'' L.f. (''Erica abietina'' subsp. ''aurantiaca'' E.G.H.Oliv. & I.M.Oliv.; ''Erica abietina'' subsp. ''perfoliosa'' E.G.H.Oliv. & I.M.Oliv.) and '' Erica situshiemalis'' E.G.H.Oliv. & Pirie.

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Daboecia
''Daboecia'' , or St. Dabeoc's heath, is a small genus of flowering plants in the family Ericaceae, containing two evergreen shrubs, closely related to the genus ''Erica''. They are native to cliffs and heathland in southern Atlantic Europe and the Azores. Description They produce urn-shaped flowers in shades of white, pink and red. ''Daboecia'' differ from European ''Erica'' species in having a substantially larger corolla. The leaves are always alternate in ''Daboecia'', never whorled. The generic name comes from the Irish Saint Dabheog. Distribution ''Daboecia'' has an oceanic distribution in western Europe, including western Ireland, western France, northwestern Spain, northwestern mainland Portugal and the Central Group of the Azores. Like ''Erica'' and ''Calluna'' species, ''Daboecia'' are calcifuges, but will tolerate neutral soils and avoid peat. Species * ''Daboecia azorica'' Tutin & E. F.

Plastid
The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a membrane-bound organelle found in the Cell (biology), cells of plants, algae, and some other eukaryotic organisms. They are considered to be intracellular endosymbiotic cyanobacteria. Examples include chloroplasts (used for photosynthesis), chromoplasts (used for pigment synthesis and storage), and leucoplasts (non-pigmented plastids that can sometimes differentiate). The event which led to permanent endosymbiosis in the Archaeplastida clade (of Embryophyte, land plants, red algae, and green algae) probably occurred with a cyanobiont (a symbiotic cyanobacteria) related to the genus ''Gloeomargarita lithophora, Gloeomargarita'', around 1.5 billion years ago. A later primary endosymbiosis event occurred in photosynthetic ''Paulinella'' amoeboids about 90–140 million years ago. This plastid belongs to the "PS-clade" (of the cyanobacteria genera ''Prochlorococcus'' and ''Synechococcus''). Chloroplas ...

Ribosomal
Ribosomes ( ) are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the ''translational apparatus''. Overview The sequence of DNA that encodes the sequence of the amino acids in a protein is transcribed into a messenger RNA chain. Ribosomes bind to messenger RNAs and use their sequences for determining the correct sequence of amino acids to generate a given protein. Amino acids are selected and carried to the ribosome by transfer RNA (tRNA) molecules, which enter the ribosome and bind to the messenger RNA chain via an anti-codon ...
