| char | The remains of solid biomass that has been incompletely combusted, such as charcoal if wood is incompletely burned. (05 Dec 1998) |

| Chara | <organism> Class of filamentous green algae exemplified by the genus Chara, in which the mitotic spindle is not surrounded by a nuclear envelope. Probably the closest relatives, among the algae, to higher plants. The giant internodal cells (up to 5cm long) exhibit dramatic cyclosis and have been much used for studies on ion transport and cytoplasmic streaming. (21 May 1997) |
| Characean algae | <organism> Class of filamentous green algae exemplified by the genus Chara, in which the mitotic spindle is not surrounded by a nuclear envelope. Probably the closest relatives, among the algae, to higher plants. The giant internodal cells (up to 5cm long) exhibit dramatic cyclosis and have been much used for studies on ion transport and cytoplasmic streaming. (21 May 1997) |
| character | In current usage, approximately equivalent to personality. The sum of the relatively fixed personality traits and habitual modes of response of an individual. (12 Dec 1998) |
| character analysis | Analysis of the defenses and personality traits that characterise an individual. (05 Mar 2000) |
| character armor | A habitual pattern of organised defenses against anxiety. (05 Mar 2000) |
| character disorder | A term referring to a group of behavioural disorder's, now replaced by a more general term, personality disorder, of which character disorder's are now a subclass. (05 Mar 2000) |

| characteristic | Synonym: character. 2. Typical or distinctive of a particular disorder. (05 Mar 2000) |
| characteristic curve | Sensitometric curve of radiographic film, a plot of the film density versus the logarithm of the relative exposure. Synonym: H and D curve, Hunter and Driffield curve. (05 Mar 2000) |
| characteristic emission | Monochromatic radiation that is produced when an electron is ejected from an atom and another takes its place by jumping from another shell; the energy of the photon is the difference between that of the two shell positions. Synonym: characteristic emission. (05 Mar 2000) |
| characteristic radiation | Monochromatic radiation that is produced when an electron is ejected from an atom and another takes its place by jumping from another shell; the energy of the photon is the difference between that of the two shell positions. Synonym: characteristic emission. (05 Mar 2000) |
| characteristic X-ray | <microscopy> An X-ray having a unique energy that is emitted by an atom in the sample during its de-energization after ionization of one of its electrons by an incident electron. (05 Aug 1998) |
| characterization | The discernment, description, or attributing of distinguishing traits. (05 Mar 2000) |
| characterizing group | A group of atoms in a molecule that distinguishes the class of substances in which it occurs from all other classes; thus carbonyl (CO) is the characterizing group of ketones; COOH, of organic acids, etc. (05 Mar 2000) |
