| kingdom | <biology> The highest taxonomic rank, immediately above phylum or division. There are five biological kingoms: 1. Kingdom animalia: The members of this kingom are complex, multicellular, eukaryotic organisms that digest food outside their cells and then absorb the digested nutrients. Animals must consume other organisms to obtain most of their nutrients. 2. Kingdom fungi: Kingdom Fungi includes organisms such as slime moulds, mushrooms, smuts, rusts, mildews, moulds, stinkhorns, puffballs, truffles and yeasts. Allare classified in this kingdom because they absorb food in solution directly through their cell walls and reproduce through spores. None conduct photosynthesis. 3. Kingdom monera: This is the most primitive of the five kingdoms, it encompasses all the bacteria. Monerans are single-celled prokaryotic organisms. 4. Kingdom plantae: The members of this kingdom are multicellular, eukaryotic organisms that (usually) conduct photosynthesis. 5. Kingdom protista: This kingdom is composed of single-celled (sometimes multicellular), eukaryotic organisms. Protists are more complex than bacteria and include protozooans and some types of algae.

| 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.

| vascular plant | A plant which possesses a well-developed system of conducting tissue to transport water, mineral salts and sugars. (09 Oct 1997) |
| gene expression regulation, plant | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in plants. (12 Dec 1998) |
| genes, plant | The hereditary material of plants. (12 Dec 1998) |
| genes, structural, plant | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of plant cells. (12 Dec 1998) |
| genome, plant | The complete gene complement contained in a set of chromosomes in a plant. (12 Dec 1998) |
| RNA, plant | Ribonucleic acid in plants having regulatory and catalytic roles as well as involvement in protein synthesis. (12 Dec 1998) |
| photosynthetic reaction centre, plant | A system consisting of proteins and cofactors which facilitates light energy and electron transfer in plants. (12 Dec 1998) |
| water plant | A plant that grows in water; an aquatic plant. Source: Websters Dictionary (01 Mar 1998) |
| pioneer plant | Plants that colonise disturbed sites or raw mineral soils and make them easier for succeeding plants species to grow in. (09 Oct 1997) |
| combined-cycle power plant | The combination of a gas turbine and a steam turbine in an electric generation plant. The waste heat from the gas turbine provides the heat energy for the steam turbine. (05 Dec 1998) |
