| indigo | Origin: F. Indigo, Sp. Indigo, indico, L. Indicum indigo, fr. Indicus Indian. See Indian. 1. A kind of deep blue, one of the seven prismatic colours. 2. <chemistry> A blue dyestuff obtained from several plants belonging to very different genera and orders; as, the woad, Isatis tinctoria, Indigofera tinctoria, I. Anil, Nereum tinctorium, etc. It is a dark blue earthy substance, tasteless and odorless, with a copper-violet luster when rubbed. Indigo does not exist in the plants as such, but is obtained by decomposition of the glycoside indican. Commercial indigo contains the essential colouring principle indigo blue or indigotine, with several other dyes; as, indigo red, indigo brown, etc, and various impurities. Indigo is insoluble in ordinary reagents, with the exception of strong sulphuric acid. <botany> Chinese indigo, the American herb Baptisia tinctoria which yields a poor quality of indigo, as do several other species of the same genus. Having the colour of, pertaining to, or derived from, indigo. <botany> Indigo berry, the gopher snake. Indigo white, a white crystalline powder obtained by reduction from indigo blue, and by oxidation easily changed back to it; called also indigogen. Indigo yellow, a substance obtained from indigo.

| indigo carmine | <chemical> 3,3'-dioxo-(delta-2,2'-biindoline)-5,5'-disulfonic acid disodium salt. An indolesulfonic acid that is used as a dye in renal function testing and as a reagent for the detection of nitrates and chlorates and in the testing of milk. Pharmacological action: dyes, indicators and reagents, renal agents. Chemical name: 1H-Indole-5-sulfonic acid, 2-(1,3-dihydro-3-oxo-5-sulfo-2H-indol-2-ylidene)-2,3-dihydro-3-oxo-, disodium salt (12 Dec 1998) |
| air plant | <botany> A plant deriving its sustenance from the air alone; an aerophyte. The "Florida moss" (Tillandsia), many tropical orchids, and most mosses and lichens are air plants. Those which are lodged upon trees, but not parasitic on them, are epiphytes. Source: Websters Dictionary (01 Mar 1998) |
| aquatic plant | <botany> Plants that must grow in water whether rooted in the mud or floating without anchorage, plants that must complete part or all of their life cycle in or near the water. (09 Oct 1997) |
| C3 plant | <plant biology> Plants that fix carbon dioxide in photosynthesis by the Calvin Benson cycle. The enzyme responsible for carbon dioxide fixation is RuDP carboxylase, whose products are compounds containing three carbon atoms. C3 plants are typical of temperate climates. Photorespiration in these plants is high. (07 Nov 1997) |
| C4 plant | <plant biology> Plants found principally in hot climates whose initial fixation of carbon dioxide in photosynthesis is by the HSK pathway. The enzyme responsible is PEP carboxylase, whose products contain four carbon atoms. Subsequently the carbon dioxide is released and re fixed by the Calvin Benson cycle. The presence of the HSK pathway permits efficient photosynthesis at high light intensities and low carbon dioxide concentrations. most species of this type have little or no photorespiration.
