| centriole | <cell biology> They are self-replicating, short, fibrous, rod-shaped organelles of animal cells. Each centriole is a short cylinder containing nine pairs of peripheral microtubules, arranged orthogonally so as to form the wall of the cylinder. Almost identical to basal body of cilium. The pericentriolar material, but not the centriole itself, is the major microtubule organising centre of the cell. Centrioles divide prior to mitosis and the daughter centrioles and their associated pericentriolar material come to lie at the poles of the spindle. (25 Jun 1999) |

| centigrade |
The degree Celsius (°C) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701–1744), who first proposed a similar system in 1742. The Celsius temperature scale was designed so that the freezing point of water is 0 degrees, and the boiling point is 100 degrees at standard atmospheric pressure. ...
