2. In immunology, the movement of granulocytes or macrophages to higher concentrations of agents known as cytotaxins.
3. Response of living cells or free-swimming micro-organisms to chemical substances in solution.
chemotaxonomy, chemotaxonomic
1. In botany, the process and methods of classifying plants based on a chemical analysis of their products.
2. Classification of organisms based on differences at the biochemical level, especially in the amino acid sequences of common proteins. Also called chemosystematics.
clinotaxis, clinotactic; klinotaxis, klinotactic
1. A directed reaction or orientation response of a motile organism to a gradient of stimulation.

The influence of one cell on another.

A form of energy, totally unrelated to electricity, light, heat, or sound, which is generated by living tissues; the vital principle in all living tissues. The term was first introduced in 1923 by Frederic Wood Jones, who defined it as "the influence of body cells on other body cells"; the “call of cell to cell”.
